Arrays created with the -optional hash function can often find elements with a single lookup. The -<a href='#cups_array_t'><code>cups_array_t</code></a> type is used when -referring to a CUPS array.</p> - -<p>The CUPS scheduler (<tt>cupsd</tt>) and many of the CUPS API -functions use the array API to efficiently manage large lists of -data.</p> - -<h3><a name='MANAGING_ARRAYS'>Managing Arrays</a></h3> - -<p>Arrays are created using either the -<a href='#cupsArrayNew'><code>cupsArrayNew</code></a>, -<a href='#cupsArrayNew2'><code>cupsArrayNew2</code></a>, or -<a href='#cupsArrayNew2'><code>cupsArrayNew3</code></a> functions. The -first function creates a new array with the specified callback function -and user data pointer:</p> - -<pre class='example'> -#include <cups/array.h> - -static int compare_func(void *first, void *second, void *user_data); - -void *user_data; -<a href='#cups_array_t'>cups_array_t</a> *array = <a href='#cupsArrayNew'>cupsArrayNew</a>(compare_func, user_data); -</pre> - -<p>The comparison function (type -<a href="#cups_arrayfunc_t"><code>cups_arrayfunc_t</code></a>) is called -whenever an element is added to the array and can be <code>NULL</code> to -create an unsorted array. The function returns -1 if the first element should -come before the second, 0 if the first and second elements should have the same -ordering, and 1 if the first element should come after the second.</p> - -<p>The "user_data" pointer is passed to your comparison function. Pass -<code>NULL</code> if you do not need to associate the elements in your array -with additional information.</p> - -<p>The <a href='#cupsArrayNew2'><code>cupsArrayNew2</code></a> function adds -two more arguments to support hashed lookups, which can potentially provide -instantaneous ("O(1)") lookups in your array:</p> - -<pre class='example'> -#include <cups/array.h> - -#define HASH_SIZE 512 /* Size of hash table */ - -static int compare_func(void *first, void *second, void *user_data); -static int hash_func(void *element, void *user_data); - -void *user_data; -<a href='#cups_array_t'>cups_array_t</a> *hash_array = <a href='#cupsArrayNew2'>cupsArrayNew2</a>(compare_func, user_data, hash_func, HASH_SIZE); -</pre> - -<p>The hash function (type -<a href="#cups_ahash_func_t"><code>cups_ahash_func_t</code></a>) should return a -number from 0 to (hash_size-1) that (hopefully) uniquely identifies the -element and is called whenever you look up an element in the array with -<a href='#cupsArrayFind'><code>cupsArrayFind</code></a>. The hash size is -only limited by available memory, but generally should not be larger than -16384 to realize any performance improvement.</p> - -<p>The <a href='#cupsArrayNew3'><code>cupsArrayNew3</code></a> function adds -copy and free callbacks to support basic memory management of elements:</p> - -<pre class='example'> -#include <cups/array.h> - -#define HASH_SIZE 512 /* Size of hash table */ - -static int compare_func(void *first, void *second, void *user_data); -static void *copy_func(void *element, void *user_data); -static void free_func(void *element, void *user_data); -static int hash_func(void *element, void *user_data); - -void *user_data; -<a href='#cups_array_t'>cups_array_t</a> *array = <a href='#cupsArrayNew3'>cupsArrayNew3</a>(compare_func, user_data, NULL, 0, copy_func, free_func); - -<a href='#cups_array_t'>cups_array_t</a> *hash_array = <a href='#cupsArrayNew3'>cupsArrayNew3</a>(compare_func, user_data, hash_func, HASH_SIZE, copy_func, free_func); -</pre> - -<p>Once you have created the array, you add elements using the -<a href='#cupsArrayAdd'><code>cupsArrayAdd</code></a> -<a href='#cupsArrayInsert'><code>cupsArrayInsert</code></a> functions. -The first function adds an element to the array, adding the new element -after any elements that have the same order, while the second inserts the -element before others with the same order. For unsorted arrays, -<a href='#cupsArrayAdd'><code>cupsArrayAdd</code></a> appends the element to -the end of the array while -<a href='#cupsArrayInsert'><code>cupsArrayInsert</code></a> inserts the -element at the beginning of the array. For example, the following code -creates a sorted array of character strings:</p> - -<pre class='example'> -#include <cups/array.h> - -/* Use strcmp() to compare strings - it will ignore the user_data pointer */ -<a href='#cups_array_t'>cups_array_t</a> *array = <a href='#cupsArrayNew'>cupsArrayNew</a>((<a href='#cups_array_func_t'>cups_array_func_t</a>)strcmp, NULL); - -/* Add four strings to the array */ -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "One Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Two Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Red Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Blue Fish"); -</pre> - -<p>Elements are removed using the -<a href='#cupsArrayRemove'><code>cupsArrayRemove</code></a> function, for -example:</p> - -<pre class='example'> -#include <cups/array.h> - -/* Use strcmp() to compare strings - it will ignore the user_data pointer */ -<a href='#cups_array_t'>cups_array_t</a> *array = <a href='#cupsArrayNew'>cupsArrayNew</a>((<a href='#cups_array_func_t'>cups_array_func_t</a>)strcmp, NULL); - -/* Add four strings to the array */ -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "One Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Two Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Red Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Blue Fish"); - -/* Remove "Red Fish" */ -<a href='#cupsArrayRemove'>cupsArrayRemove</a>(array, "Red Fish"); -</pre> - -<p>Finally, you free the memory used by the array using the -<a href='#cupsArrayDelete'><code>cupsArrayDelete</code></a> function. All -of the memory for the array and hash table (if any) is freed, however <em>CUPS -does not free the elements unless you provide copy and free functions</em>.</p> - -<h3><a name='FINDING_AND_ENUMERATING'>Finding and Enumerating Elements</a></h3> - -<p>CUPS provides several functions to find and enumerate elements in an -array. Each one sets or updates a "current index" into the array, such that -future lookups will start where the last one left off:</p> - -<dl> - <dt><a href='#cupsArrayFind'><code>cupsArrayFind</code></a></dt> - <dd>Returns the first matching element.</dd> - <dt><a href='#cupsArrayFirst'><code>cupsArrayFirst</code></a></dt> - <dd>Returns the first element in the array.</dd> - <dt><a href='#cupsArrayIndex'><code>cupsArrayIndex</code></a></dt> - <dd>Returns the Nth element in the array, starting at 0.</dd> - <dt><a href='#cupsArrayLast'><code>cupsArrayLast</code></a></dt> - <dd>Returns the last element in the array.</dd> - <dt><a href='#cupsArrayNext'><code>cupsArrayNext</code></a></dt> - <dd>Returns the next element in the array.</dd> - <dt><a href='#cupsArrayPrev'><code>cupsArrayPrev</code></a></dt> - <dd>Returns the previous element in the array.</dd> -</dl> - -<p>Each of these functions returns <code>NULL</code> when there is no -corresponding element. For example, a simple <code>for</code> loop using the -<a href='#cupsArrayFirst'><code>cupsArrayFirst</code></a> and -<a href='#cupsArrayNext'><code>cupsArrayNext</code></a> functions will -enumerate all of the strings in our previous example:</p> - -<pre class='example'> -#include <cups/array.h> - -/* Use strcmp() to compare strings - it will ignore the user_data pointer */ -<a href='#cups_array_t'>cups_array_t</a> *array = <a href='#cupsArrayNew'>cupsArrayNew</a>((<a href='#cups_array_func_t'>cups_array_func_t</a>)strcmp, NULL); - -/* Add four strings to the array */ -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "One Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Two Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Red Fish"); -<a href='#cupsArrayAdd'>cupsArrayAdd</a>(array, "Blue Fish"); - -/* Show all of the strings in the array */ -char *s; -for (s = (char *)<a href='#cupsArrayFirst'>cupsArrayFirst</a>(array); s != NULL; s = (char *)<a href='#cupsArrayNext'>cupsArrayNext</a>(array)) - puts(s); -</pre> -<h2 class="title"><a name="FUNCTIONS">Functions</a></h2> -<h3 class="function"><span class="info"> CUPS 1.2/macOS 10.5 </span><a name="cupsArrayAdd">cupsArrayAdd</a></h3> -<p class="description">Add an element to the array.</p> -<p class="code"> -int cupsArrayAdd (<br> - <a href="#cups_array_t">cups_array_t</a> *a,<br> - void *e<br> -);</p> -<h4 class="parameters">Parameters</h4> -<dl> -<dt>a</dt> -<dd class="description">Array</dd> -<dt>e</dt> -<dd class="description">Element</dd> -</dl> -<h4 class="returnvalue">Return Value</h4> -<p class="description">1 on success, 0 on failure</p> -<h4 class="discussion">Discussion</h4> -<p class="discussion">When adding an element to a sorted array, non-unique elements are -appended at the end of the run of identical elements.

You identify which server -you want to communicate with using a pointer to the opaque structure -<code>http_t</code>. All of the examples in this document use the -<code>CUPS_HTTP_DEFAULT</code> constant, referring to the default connection -to the scheduler.

For example, -if any of the job creation functions returns a job ID of 0, you can use -<a href='#cupsLastErrorString'><code>cupsLastErrorString</code></a> to show -the reason why the job could not be created:</p> - -<pre class='example'> -#include <cups/cups.h> - -int job_id; - -if (job_id == 0) - puts(cupsLastErrorString()); -</pre> - -<h3><a name='PASSWORDS_AND_AUTHENTICATION'>Passwords and Authentication</a></h3> - -<p>CUPS supports authentication of any request, including submission of print -jobs. The default mechanism for getting the username and password is to use the -login user and a password from the console.</p> - -<p>To support other types of applications, in particular Graphical User -Interfaces ("GUIs"), the CUPS API provides functions to set the default -username and to register a callback function that returns a password string.</p> - -<p>The <a href="#cupsSetPasswordCB"><code>cupsSetPasswordCB</code></a> -function is used to set a password callback in your program. Only one -function can be used at any time.</p> - -<p>The <a href="#cupsSetUser"><code>cupsSetUser</code></a> function sets the -current username for authentication. This function can be called by your -password callback function to change the current username as needed.</p> - -<p>The following example shows a simple password callback that gets a -username and password from the user:</p> - -<pre class='example'> -#include <cups/cups.h> - -const char * -my_password_cb(const char *prompt) -{ - char user[65]; - - - puts(prompt); - - /* Get a username from the user */ - printf("Username: "); - if (fgets(user, sizeof(user), stdin) == NULL) - return (NULL); - - /* Strip the newline from the string and set the user */ - user[strlen(user) - 1] = '\0'; - - <a href='#cupsSetUser'>cupsSetUser</a>(user); - - /* Use getpass() to ask for the password... */ - return (getpass("Password: ")); -} - -<a href='#cupsSetPasswordCB'>cupsSetPasswordCB</a>(my_password_cb); -</pre> - -<p>Similarly, a GUI could display the prompt string in a window with input -fields for the username and password.

They are typically used by monitoring and -administration programs to perform specific functions not supported by the -high-level CUPS API functions.</p> - -<p>The HTTP APIs use an opaque structure called -<a href='#http_t'><code>http_t</code></a> to manage connections to -a particular HTTP or IPP server. The -<a href='#httpConnectEncrypt'><code>httpConnectEncrypt</code></a> function is -used to create an instance of this structure for a particular server. -The constant <code>CUPS_HTTP_DEFAULT</code> can be used with all of the -<code>cups</code> functions to refer to the default CUPS server - the functions -create a per-thread <a href='#http_t'><code>http_t</code></a> as needed.</p> - -<p>The IPP APIs use two opaque structures for requests (messages sent to the CUPS scheduler) and responses (messages sent back to your application from the scheduler). The <a href='#ipp_t'><code>ipp_t</code></a> type holds a complete request or response and is allocated using the <a href='#ippNew'><code>ippNew</code></a> or <a href='#ippNewRequest'><code>ippNewRequest</code></a> functions and freed using the <a href='#ippDelete'><code>ippDelete</code></a> function.</p> - -<p>The second opaque structure is called <a href='#ipp_attribute_t'><code>ipp_attribute_t</code></a> and holds a single IPP attribute which consists of a group tag (<a href='#ippGetGroupTag'><code>ippGetGroupTag</code></a>), a value type tag (<a href='#ippGetValueTag'><code>ippGetValueTag</code></a>), the attribute name (<a href='#ippGetName'><code>ippGetName</code></a>), and 1 or more values (<a href='#ippGetCount'><code>ippGetCount</code></a>, <a href='#ippGetBoolean'><code>ippGetBoolean</code></a>, <a href='#ippGetCollection'><code>ippGetCollection</code></a>, <a href='#ippGetDate'><code>ippGetDate</code></a>, <a href='#ippGetInteger'><code>ippGetInteger</code></a>, <a href='#ippGetRange'><code>ippGetRange</code></a>, <a href='#ippGetResolution'><code>ippGetResolution</code></a>, and <a href='#ippGetString'><code>ippGetString</code></a>). Attributes are added to an <a href='#ipp_t'><code>ipp_t</code></a> pointer using one of the <code>ippAdd</code> functions. For example, use <a href='#ippAddString'><code>ippAddString</code></a> to add the "printer-uri" and "requesting-user-name" string attributes to a request:</p> - -<pre class='example'> -<a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); - -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", - NULL, "ipp://localhost/printers/"); -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", - NULL, cupsUser()); -</pre> - -<p>Once you have created an IPP request, use the <code>cups</code> functions to send the request to and read the response from the server. For example, the <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function can be used for simple query operations that do not involve files:</p> - -<pre class='example'> -#include <cups/cups.h> - - -<a href='#ipp_t'>ipp_t</a> *<a name='get_jobs'>get_jobs</a>(void) -{ - <a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_GET_JOBS); - - <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", - NULL, "ipp://localhost/printers/"); - <a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", - NULL, cupsUser()); - - return (<a href='#cupsDoRequest'>cupsDoRequest</a>(CUPS_HTTP_DEFAULT, request, "/")); -} -</pre> - -<p>The <a href='#cupsDoRequest'><code>cupsDoRequest</code></a> function frees the request and returns an IPP response or <code>NULL</code> pointer if the request could not be sent to the server. Once you have a response from the server, you can either use the <a href='#ippFindAttribute'><code>ippFindAttribute</code></a> and <a href='#ippFindNextAttribute'><code>ippFindNextAttribute</code></a> functions to find specific attributes, for example:</p> - -<pre class='example'> -<a href='#ipp_t'>ipp_t</a> *response; -<a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; - -attr = <a href='#ippFindAttribute'>ippFindAttribute</a>(response, "printer-state", IPP_TAG_ENUM); -</pre> - -<p>You can also walk the list of attributes with a simple <code>for</code> loop like this:</p> - -<pre class='example'> -<a href='#ipp_t'>ipp_t</a> *response; -<a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; - -for (attr = <a href='#ippFirstAttribute'>ippFirstAttribute</a>(response); attr != NULL; attr = <a href='#ippNextAttribute'>ippNextAttribute</a>(response)) - if (ippGetName(attr) == NULL) - puts("--SEPARATOR--"); - else - puts(ippGetName(attr)); -</pre> - -<p>The <code>for</code> loop approach is normally used when collecting attributes for multiple objects (jobs, printers, etc.) in a response. Attributes with <code>NULL</code> names indicate a separator between the attributes of each object. For example, the following code will list the jobs returned from our previous <a href='#get_jobs'><code>get_jobs</code></a> example code:</p> - -<pre class='example'> -<a href='#ipp_t'>ipp_t</a> *response = <a href='#get_jobs'>get_jobs</a>(); - -if (response != NULL) -{ - <a href='#ipp_attribute_t'>ipp_attribute_t</a> *attr; - const char *attrname; - int job_id = 0; - const char *job_name = NULL; - const char *job_originating_user_name = NULL; - - puts("Job ID Owner Title"); - puts("------ ---------------- ---------------------------------"); - - for (attr = <a href='#ippFirstAttribute'>ippFirstAttribute</a>(response); attr != NULL; attr = <a href='#ippNextAttribute'>ippNextAttribute</a>(response)) - { - /* Attributes without names are separators between jobs */ - attrname = ippGetName(attr); - if (attrname == NULL) - { - if (job_id > 0) - { - if (job_name == NULL) - job_name = "(withheld)"; - - if (job_originating_user_name == NULL) - job_originating_user_name = "(withheld)"; - - printf("%5d %-16s %s\n", job_id, job_originating_user_name, job_name); - } - - job_id = 0; - job_name = NULL; - job_originating_user_name = NULL; - continue; - } - else if (!strcmp(attrname, "job-id") && ippGetValueTag(attr) == IPP_TAG_INTEGER) - job_id = ippGetInteger(attr, 0); - else if (!strcmp(attrname, "job-name") && ippGetValueTag(attr) == IPP_TAG_NAME) - job_name = ippGetString(attr, 0, NULL); - else if (!strcmp(attrname, "job-originating-user-name") && - ippGetValueTag(attr) == IPP_TAG_NAME) - job_originating_user_name = ippGetString(attr, 0, NULL); - } - - if (job_id > 0) - { - if (job_name == NULL) - job_name = "(withheld)"; - - if (job_originating_user_name == NULL) - job_originating_user_name = "(withheld)"; - - printf("%5d %-16s %s\n", job_id, job_originating_user_name, job_name); - } -} -</pre> - -<h3><a name='CREATING_URI_STRINGS'>Creating URI Strings</a></h3> - -<p>To ensure proper encoding, the -<a href='#httpAssembleURIf'><code>httpAssembleURIf</code></a> function must be -used to format a "printer-uri" string for all printer-based requests:</p> - -<pre class='example'> -const char *name = "Foo"; -char uri[1024]; -<a href='#ipp_t'>ipp_t</a> *request; - -<a href='#httpAssembleURIf'>httpAssembleURIf</a>(HTTP_URI_CODING_ALL, uri, sizeof(uri), "ipp", NULL, cupsServer(), - ippPort(), "/printers/%s", name); -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", NULL, uri); -</pre> - -<h3><a name='SENDING_REQUESTS_WITH_FILES'>Sending Requests with Files</a></h3> - -<p>The <a href='#cupsDoFileRequest'><code>cupsDoFileRequest</code></a> and -<a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> functions are -used for requests involving files. The -<a href='#cupsDoFileRequest'><code>cupsDoFileRequest</code></a> function -attaches the named file to a request and is typically used when sending a print -file or changing a printer's PPD file:</p> - -<pre class='example'> -const char *filename = "/usr/share/cups/data/testprint.ps"; -const char *name = "Foo"; -char uri[1024]; -char resource[1024]; -<a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(IPP_PRINT_JOB); -<a href='#ipp_t'>ipp_t</a> *response; - -/* Use httpAssembleURIf for the printer-uri string */ -<a href='#httpAssembleURIf'>httpAssembleURIf</a>(HTTP_URI_CODING_ALL, uri, sizeof(uri), "ipp", NULL, cupsServer(), - ippPort(), "/printers/%s", name); -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_URI, "printer-uri", NULL, uri); -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "requesting-user-name", - NULL, cupsUser()); -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "job-name", - NULL, "testprint.ps"); - -/* Use snprintf for the resource path */ -snprintf(resource, sizeof(resource), "/printers/%s", name); - -response = <a href='#cupsDoFileRequest'>cupsDoFileRequest</a>(CUPS_HTTP_DEFAULT, request, resource, filename); -</pre> - -<p>The <a href='#cupsDoIORequest'><code>cupsDoIORequest</code></a> function -optionally attaches a file to the request and optionally saves a file in the -response from the server. It is used when using a pipe for the request -attachment or when using a request that returns a file, currently only -<code>CUPS_GET_DOCUMENT</code> and <code>CUPS_GET_PPD</code>. For example, -the following code will download the PPD file for the sample HP LaserJet -printer driver:</p> - -<pre class='example'> -char tempfile[1024]; -int tempfd; -<a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(CUPS_GET_PPD); -<a href='#ipp_t'>ipp_t</a> *response; - -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "ppd-name", - NULL, "laserjet.ppd"); - -tempfd = cupsTempFd(tempfile, sizeof(tempfile)); - -response = <a href='#cupsDoIORequest'>cupsDoIORequest</a>(CUPS_HTTP_DEFAULT, request, "/", -1, tempfd); -</pre> - -<p>The example passes <code>-1</code> for the input file descriptor to specify -that no file is to be attached to the request.

Unlike the other request -functions, the IPP request is not automatically freed, so remember to -free your request with the <a href='#ippDelete'><code>ippDelete</code></a> -function.</p> - -<p>File data is attached to the request using the -<a href='#cupsWriteRequestData'><code>cupsWriteRequestData</code></a> -function, while file data returned from the server is read using the -<a href='#cupsReadResponseData'><code>cupsReadResponseData</code></a> -function. We can rewrite the previous <code>CUPS_GET_PPD</code> example -to use the asynchronous functions quite easily:</p> - -<pre class='example'> -char tempfile[1024]; -int tempfd; -<a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(CUPS_GET_PPD); -<a href='#ipp_t'>ipp_t</a> *response; - -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "ppd-name", - NULL, "laserjet.ppd"); - -tempfd = cupsTempFd(tempfile, sizeof(tempfile)); - -if (<a href='#cupsSendRequest'>cupsSendRequest</a>(CUPS_HTTP_DEFAULT, request, "/") == HTTP_CONTINUE) -{ - response = <a href='#cupsGetResponse'>cupsGetResponse</a>(CUPS_HTTP_DEFAULT, "/"); - - if (response != NULL) - { - ssize_t bytes; - char buffer[8192]; - - while ((bytes = <a href='#cupsReadResponseData'>cupsReadResponseData</a>(CUPS_HTTP_DEFAULT, buffer, sizeof(buffer))) > 0) - write(tempfd, buffer, bytes); - } -} - -/* Free the request! */ -<a href='#ippDelete'>ippDelete</a>(request); -</pre> - -<p>The <a href='#cupsSendRequest'><code>cupsSendRequest</code></a> function -returns the initial HTTP request status, typically either -<code>HTTP_CONTINUE</code> or <code>HTTP_UNAUTHORIZED</code>. The latter status -is returned when the request requires authentication of some sort. The -<a href='#cupsDoAuthentication'><code>cupsDoAuthentication</code></a> function -must be called when your see <code>HTTP_UNAUTHORIZED</code> and the request -re-sent. We can add authentication support to our example code by using a -<code>do ... while</code> loop:</p> - -<pre class='example'> -char tempfile[1024]; -int tempfd; -<a href='#ipp_t'>ipp_t</a> *request = <a href='#ippNewRequest'>ippNewRequest</a>(CUPS_GET_PPD); -<a href='#ipp_t'>ipp_t</a> *response; -http_status_t status; - -<a href='#ippAddString'>ippAddString</a>(request, IPP_TAG_OPERATION, IPP_TAG_NAME, "ppd-name", - NULL, "laserjet.ppd"); - -tempfd = cupsTempFd(tempfile, sizeof(tempfile)); - -/* Loop for authentication */ -do -{ - status = <a href='#cupsSendRequest'>cupsSendRequest</a>(CUPS_HTTP_DEFAULT, request, "/"); - - if (status == HTTP_UNAUTHORIZED) - { - /* Try to authenticate, break out of the loop if that fails */ - if (<a href='#cupsDoAuthentication'>cupsDoAuthentication</a>(CUPS_HTTP_DEFAULT, "POST", "/")) - break; - } -} -while (status != HTTP_CONTINUE && status != HTTP_UNAUTHORIZED); - -if (status == HTTP_CONTINUE) -{ - response = <a href='#cupsGetResponse'>cupsGetResponse</a>(CUPS_HTTP_DEFAULT, "/"); - - if (response != NULL) - { - ssize_t bytes; - char buffer[8192]; - - while ((bytes = <a href='#cupsReadResponseData'>cupsReadResponseData</a>(CUPS_HTTP_DEFAULT, buffer, sizeof(buffer))) > 0) - write(tempfd, buffer, bytes); - } -} - -/* Free the request! */ -<a href='#ippDelete'>ippDelete</a>(request); -</pre> -<h2 class="title"><a name="FUNCTIONS">Functions</a></h2> -<h3 class="function"><span class="info"> CUPS 1.1.20/macOS 10.4 </span><a name="cupsDoAuthentication">cupsDoAuthentication</a></h3> -<p class="description">Authenticate a request.</p> -<p class="code"> -int cupsDoAuthentication (<br> - <a href="#http_t">http_t</a> *http,<br> - const char *method,<br> - const char *resource<br> -);</p> -<h4 class="parameters">Parameters</h4> -<dl> -<dt>http</dt> -<dd class="description">Connection to server or <code>CUPS_HTTP_DEFAULT</code></dd> -<dt>method</dt> -<dd class="description">Request method ("GET", "POST", "PUT")</dd> -<dt>resource</dt> -<dd class="description">Resource path</dd> -</dl> -<h4 class="returnvalue">Return Value</h4> -<p class="description">0 on success, -1 on error</p> -<h4 class="discussion">Discussion</h4> -<p class="discussion">This function should be called in response to a <code>HTTP_STATUS_UNAUTHORIZED</code> -status, prior to resubmitting your request. - -</p> -<h3 class="function"><a name="cupsDoFileRequest">cupsDoFileRequest</a></h3> -<p class="description">Do an IPP request with a file.</p> -<p class="code"> -<a href="#ipp_t">ipp_t</a> *cupsDoFileRequest (<br> - <a href="#http_t">http_t</a> *http,<br> - <a href="#ipp_t">ipp_t</a> *request,<br> - const char *resource,<br> - const char *filename<br> -);</p> -<h4 class="parameters">Parameters</h4> -<dl> -<dt>http</dt> -<dd class="description">Connection to server or <code>CUPS_HTTP_DEFAULT</code></dd> -<dt>request</dt> -<dd class="description">IPP request</dd> -<dt>resource</dt> -<dd class="description">HTTP resource for POST</dd> -<dt>filename</dt> -<dd class="description">File to send or <code>NULL</code> for none</dd> -</dl> -<h4 class="returnvalue">Return Value</h4> -<p class="description">Response data</p> -<h4 class="discussion">Discussion</h4> -<p class="discussion">This function sends the IPP request and attached file to the specified -server, retrying and authenticating as necessary.

The "cups" library provides all of the common application and -filter functions while the "cupsimage" library provides all of the imaging -functions used in raster printer drivers. The "cups" library functions are -accessed by including the <var><cups/cups.h></var> header, while -"cupsimage" functions are found in the <var><cups/raster.h></var> -header.</p> - -<h2 class="title"><a name="COMPILING">Compiling Programs</a></h2> - -<p>The CUPS libraries can be used from any C, C++, or Objective C program. -The method of compiling against the libraries varies depending on the -operating system and installation of CUPS. The following sections show how -to compile a simple program (shown below) in two common environments.</p> - -<p>The following simple program lists the available printers on the system:</p> - -<pre class="example"> -#include <stdio.h> -#include <cups/cups.h> - -int main(void) -{ - int i; - cups_dest_t *dests, *dest; - int num_dests = cupsGetDests(&dests); - - for (i = num_dests, dest = dests; i > 0; i --, dest ++) - { - if (dest->instance) - printf("%s/%s\n", dest->name, dest->instance); - else - puts(dest->name); - } - - return (0); -} -</pre> - -<h3><a name="XCODE">Compiling with Xcode</a></h3> - -<p>In Xcode, choose <var>New Project...</var> from the <var>File</var> menu, -then select the <var>Standard Tool</var> project type under <var>Command Line -Utility</var>.

"cups" library to talk to the different parts of CUPS and with Internet Printing Protocol (IPP) printers. The "cups" library functions are accessed by including the <code><cups/cups.h></code> header.</p> + <p>CUPS is based on the Internet Printing Protocol ("IPP"), which allows clients (applications) to communicate with a server (the scheduler, printers, etc.) to get a list of destinations, send print jobs, and so forth. You identify which server you want to communicate with using a pointer to the opaque structure <code>http_t</code>. The <code>CUPS_HTTP_DEFAULT</code> constant can be used when you want to talk to the CUPS scheduler.</p> + <h3><a id="guidelines">Guidelines</a></h3> + <p>When writing software that uses the "cups" library:</p> + <ul> + <li>Do not use undocumented or deprecated APIs,</li> + <li>Do not rely on pre-configured printers,</li> + <li>Do not assume that printers support specific features or formats, and</li> + <li>Do not rely on implementation details (PPDs, etc.)</li> +</ul> + <p>CUPS is designed to insulate users and developers from the implementation details of printers and file formats. The goal is to allow an application to supply a print file in a standard format with the user intent ("print four copies, two-sided on A4 media, and staple each copy") and have the printing system manage the printer communication and format conversion needed.</p> + <p>Similarly, printer and job management applications can use standard query operations to obtain the status information in a common, generic form and use standard management operations to control the state of those printers and jobs.</p> + <h3><a id="terms-used-in-this-document">Terms Used in This Document</a></h3> + <p>A <em>Destination</em> is a printer or print queue that accepts print jobs. A <em>Print</em> <em>Job</em> is one or more documents that are processed by a destination using options supplied when creating the job. A <em>Document</em> is a file (JPEG image, PDF file, etc.) suitable for printing. An <em>Option</em> controls some aspect of printing, such as the media used. <em>Media</em> is the sheets or roll that is printed on. An <em>Attribute</em> is an option encoded for an Internet Printing Protocol (IPP) request.</p> + <h3><a id="compiling-programs-that-use-the-cups-api">Compiling Programs That Use the CUPS API</a></h3> + <p>The CUPS libraries can be used from any C, C++, or Objective C program. The method of compiling against the libraries varies depending on the operating system and installation of CUPS. The following sections show how to compile a simple program (shown below) in two common environments.</p> + <p>The following simple program lists the available destinations:</p> + <pre><code>#include <stdio.h> +#include <cups/cups.h> + +int print_dest(void *user_data, unsigned flags, cups_dest_t *dest) +{ + if (dest->instance) + printf("%s/%s\n", dest->name, dest->instance); + else + puts(dest->name); + + return (1); +} + +int main(void) +{ + cupsEnumDests(CUPS_DEST_FLAGS_NONE, 1000, NULL, 0, 0, print_dest, NULL); + + return (0); +} +</code></pre> + <h4><a id="compiling-with-xcode">Compiling with Xcode</a></h4> + <p>In Xcode, choose <em>New</em> <em>Project...</em> from the <em>File</em> menu (or press SHIFT+CMD+N), then select the <em>Command</em> <em>Line</em> <em>Tool</em> under the macOS Application project type. Click <em>Next</em> and enter a name for the project, for example "firstcups". Click <em>Next</em> and choose a project directory. The click <em>Next</em> to create the project.</p> + <p>In the project window, click on the <em>Build</em> <em>Phases</em> group and expand the <em>Link</em> <em>Binary</em> <em>with</em> <em>Libraries</em> section. Click <em>+</em>, type "libcups" to show the library, and then double-click on <code>libcups.tbd</code>.</p> + <p>Finally, click on the <code>main.c</code> file in the sidebar and copy the example program to the file. Build and run (CMD+R) to see the list of destinations.</p> + <h4><a id="compiling-with-gcc">Compiling with GCC</a></h4> + <p>From the command-line, create a file called <code>sample.c</code> using your favorite editor, copy the example to this file, and save. Then run the following command to compile it with GCC and run it:</p> + <pre><code>gcc -o simple `cups-config --cflags` simple.c `cups-config --libs` +./simple +</code></pre> + <p>The <code>cups-config</code> command provides the compiler flags (<code>cups-config --cflags</code>) and libraries (<code>cups-config --libs</code>) needed for the local system.</p> + <h2><a id="working-with-destinations">Working with Destinations</a></h2> + <p>Destinations, which in CUPS represent individual printers or classes (collections or pools) of printers, are represented by the <code>cups_dest_t</code> structure which includes the name (<code>name</code>), instance (<code>instance</code>, saved options/settings), whether the destination is the default for the user (<code>is_default</code>), and the options and basic information associated with that destination (<code>num_options</code> and <code>options</code>).</p> + <p>Historically destinations have been manually maintained by the administrator of a system or network, but CUPS also supports dynamic discovery of destinations on the current network.</p> + <h3><a id="finding-available-destinations">Finding Available Destinations</a></h3> + <p>The <code>cupsEnumDests</code> function finds all of the available destinations:</p> + <pre><code> int + cupsEnumDests(unsigned flags, int msec, int *cancel, + cups_ptype_t type, cups_ptype_t mask, + cups_dest_cb_t cb, void *user_data) +</code></pre> + <p>The <code>flags</code> argument specifies enumeration options, which at present must be <code>CUPS_DEST_FLAGS_NONE</code>.</p> + <p>The <code>msec</code> argument specifies the maximum amount of time that should be used for enumeration in milliseconds - interactive applications should keep this value to 5000 or less when run on the main thread.</p> + <p>The <code>cancel</code> argument points to an integer variable that, when set to a non-zero value, will cause enumeration to stop as soon as possible. It can be <code>NULL</code> if not needed.</p> + <p>The <code>type</code> and <code>mask</code> arguments are bitfields that allow the caller to filter the destinations based on categories and/or capabilities. The destination's "printer-type" value is masked by the <code>mask</code> value and compared to the <code>type</code> value when filtering. For example, to only enumerate destinations that are hosted on the local system, pass <code>CUPS_PRINTER_LOCAL</code> for the <code>type</code> argument and <code>CUPS_PRINTER_DISCOVERED</code> for the <code>mask</code> argument. The following constants can be used for filtering:</p> + <ul> + <li><code>CUPS_PRINTER_CLASS</code>: A collection of destinations.</li> + <li><code>CUPS_PRINTER_FAX</code>: A facsimile device.</li> + <li><code>CUPS_PRINTER_LOCAL</code>: A local printer or class. This constant has the value 0 (no bits set) and is only used for the <code>type</code> argument and is paired with the <code>CUPS_PRINTER_REMOTE</code> or <code>CUPS_PRINTER_DISCOVERED</code> constant passed in the <code>mask</code> argument.</li> + <li><code>CUPS_PRINTER_REMOTE</code>: A remote (shared) printer or class.</li> + <li><code>CUPS_PRINTER_DISCOVERED</code>: An available network printer or class.</li> + <li><code>CUPS_PRINTER_BW</code>: Can do B&W printing.</li> + <li><code>CUPS_PRINTER_COLOR</code>: Can do color printing.</li> + <li><code>CUPS_PRINTER_DUPLEX</code>: Can do two-sided printing.</li> + <li><code>CUPS_PRINTER_STAPLE</code>: Can staple output.</li> + <li><code>CUPS_PRINTER_COLLATE</code>: Can quickly collate copies.</li> + <li><code>CUPS_PRINTER_PUNCH</code>: Can punch output.</li> + <li><code>CUPS_PRINTER_COVER</code>: Can cover output.</li> + <li><code>CUPS_PRINTER_BIND</code>: Can bind output.</li> + <li><code>CUPS_PRINTER_SORT</code>: Can sort output (mailboxes, etc.)</li> + <li><code>CUPS_PRINTER_SMALL</code>: Can print on Letter/Legal/A4-size media.</li> + <li><code>CUPS_PRINTER_MEDIUM</code>: Can print on Tabloid/B/C/A3/A2-size media.</li> + <li><code>CUPS_PRINTER_LARGE</code>: Can print on D/E/A1/A0-size media.</li> + <li><code>CUPS_PRINTER_VARIABLE</code>: Can print on rolls and custom-size media.</li> +</ul> + <p>The <code>cb</code> argument specifies a function to call for every destination that is found:</p> + <pre><code>typedef int (*cups_dest_cb_t)(void *user_data, + unsigned flags, + cups_dest_t *dest); +</code></pre> + <p>The callback function receives a copy of the <code>user_data</code> argument along with a bitfield (<code>flags</code>) and the destination that was found. The <code>flags</code> argument can have any of the following constant (bit) values set:</p> + <ul> + <li><code>CUPS_DEST_FLAGS_MORE</code>: There are more destinations coming.</li> + <li><code>CUPS_DEST_FLAGS_REMOVED</code>: The destination has gone away and should be removed from the list of destinations a user can select.</li> + <li><code>CUPS_DEST_FLAGS_ERROR</code>: An error occurred. The reason for the error can be found by calling the <code>cupsLastError</code> and/or <code>cupsLastErrorString</code> functions.</li> +</ul> + <p>The callback function returns 0 to stop enumeration or 1 to continue.</p> + <blockquote> + <p>Note that the callback function will likely be called multiple times for the same destination, so it is up to the caller to suppress any duplicate destinations.</p> +</blockquote> + <p>The following example shows how to use <code>cupsEnumDests</code> to get a filtered array of destinations:</p> + <pre><code>typedef struct +{ + int num_dests; + cups_dest_t *dests; +} my_user_data_t; + +int +my_dest_cb(my_user_data_t *user_data, unsigned flags, + cups_dest_t *dest) +{ + if (flags & CUPS_DEST_FLAGS_REMOVED) + { + /* + * Remove destination from array... + */ + + user_data->num_dests = + cupsRemoveDest(dest->name, dest->instance, + user_data->num_dests, + &(user_data->dests)); + } + else + { + /* + * Add destination to array... + */ + + user_data->num_dests = + cupsCopyDest(dest, user_data->num_dests, + &(user_data->dests)); + } + + return (1); +} + +int +my_get_dests(cups_ptype_t type, cups_ptype_t mask, + cups_dest_t **dests) +{ + my_user_data_t user_data = { 0, NULL }; + + if (!cupsEnumDests(CUPS_DEST_FLAGS_NONE, 1000, NULL, type, + mask, (cups_dest_cb_t)my_dest_cb, + &user_data)) + { + /* + * An error occurred, free all of the destinations and + * return... + */ + + cupsFreeDests(user_data.num_dests, user_dasta.dests); + + *dests = NULL; + + return (0); + } + + /* + * Return the destination array... + */ + + *dests = user_data.dests; + + return (user_data.num_dests); +} +</code></pre> + <h3><a id="basic-destination-information">Basic Destination Information</a></h3> + <p>The <code>num_options</code> and <code>options</code> members of the <code>cups_dest_t</code> structure provide basic attributes about the destination in addition to the user default options and values for that destination. The following names are predefined for various destination attributes:</p> + <ul> + <li>"auth-info-required": The type of authentication required for printing to this destination: "none", "username,password", "domain,username,password", or "negotiate" (Kerberos).</li> + <li>"printer-info": The human-readable description of the destination such as "My Laser Printer".</li> + <li>"printer-is-accepting-jobs": "true" if the destination is accepting new jobs, "false" otherwise.</li> + <li>"printer-is-shared": "true" if the destination is being shared with other computers, "false" otherwise.</li> + <li>"printer-location": The human-readable location of the destination such as "Lab 4".</li> + <li>"printer-make-and-model": The human-readable make and model of the destination such as "ExampleCorp LaserPrinter 4000 Series".</li> + <li>"printer-state": "3" if the destination is idle, "4" if the destination is printing a job, and "5" if the destination is stopped.</li> + <li>"printer-state-change-time": The UNIX time when the destination entered the current state.</li> + <li>"printer-state-reasons": Additional comma-delimited state keywords for the destination such as "media-tray-empty-error" and "toner-low-warning".</li> + <li>"printer-type": The <code>cups_ptype_t</code> value associated with the destination.</li> + <li>"printer-uri-supported": The URI associated with the destination; if not set, this destination was discovered but is not yet setup as a local printer.</li> +</ul> + <p>Use the <code>cupsGetOption</code> function to retrieve the value. For example, the following code gets the make and model of a destination:</p> + <pre><code>const char *model = cupsGetOption("printer-make-and-model", + dest->num_options, + dest->options); +</code></pre> + <h3><a id="detailed-destination-information">Detailed Destination Information</a></h3> + <p>Once a destination has been chosen, the <code>cupsCopyDestInfo</code> function can be used to gather detailed information about the destination:</p> + <pre><code>cups_dinfo_t * +cupsCopyDestInfo(http_t *http, cups_dest_t *dest); +</code></pre> + <p>The <code>http</code> argument specifies a connection to the CUPS scheduler and is typically the constant <code>CUPS_HTTP_DEFAULT</code>. The <code>dest</code> argument specifies the destination to query.</p> + <p>The <code>cups_dinfo_t</code> structure that is returned contains a snapshot of the supported options and their supported, ready, and default values. It also can report constraints between different options and values, and recommend changes to resolve those constraints.</p> + <h4><a id="getting-supported-options-and-values">Getting Supported Options and Values</a></h4> + <p>The <code>cupsCheckDestSupported</code> function can be used to test whether a particular option or option and value is supported:</p> + <pre><code>int +cupsCheckDestSupported(http_t *http, cups_dest_t *dest, + cups_dinfo_t *info, + const char *option, + const char *value); +</code></pre> + <p>The <code>option</code> argument specifies the name of the option to check. The following constants can be used to check the various standard options:</p> + <ul> + <li><code>CUPS_COPIES</code>: Controls the number of copies that are produced.</li> + <li><code>CUPS_FINISHINGS</code>: A comma-delimited list of integer constants that control the finishing processes that are applied to the job, including stapling, punching, and folding.</li> + <li><code>CUPS_MEDIA</code>: Controls the media size that is used, typically one of the following: <code>CUPS_MEDIA_3X5</code>, <code>CUPS_MEDIA_4X6</code>, <code>CUPS_MEDIA_5X7</code>, <code>CUPS_MEDIA_8X10</code>, <code>CUPS_MEDIA_A3</code>, <code>CUPS_MEDIA_A4</code>, <code>CUPS_MEDIA_A5</code>, <code>CUPS_MEDIA_A6</code>, <code>CUPS_MEDIA_ENV10</code>, <code>CUPS_MEDIA_ENVDL</code>, <code>CUPS_MEDIA_LEGAL</code>, <code>CUPS_MEDIA_LETTER</code>, <code>CUPS_MEDIA_PHOTO_L</code>, <code>CUPS_MEDIA_SUPERBA3</code>, or <code>CUPS_MEDIA_TABLOID</code>.</li> + <li><code>CUPS_MEDIA_SOURCE</code>: Controls where the media is pulled from, typically either <code>CUPS_MEDIA_SOURCE_AUTO</code> or <code>CUPS_MEDIA_SOURCE_MANUAL</code>.</li> + <li><code>CUPS_MEDIA_TYPE</code>: Controls the type of media that is used, typically one of the following: <code>CUPS_MEDIA_TYPE_AUTO</code>, <code>CUPS_MEDIA_TYPE_ENVELOPE</code>, <code>CUPS_MEDIA_TYPE_LABELS</code>, <code>CUPS_MEDIA_TYPE_LETTERHEAD</code>, <code>CUPS_MEDIA_TYPE_PHOTO</code>, <code>CUPS_MEDIA_TYPE_PHOTO_GLOSSY</code>, <code>CUPS_MEDIA_TYPE_PHOTO_MATTE</code>, <code>CUPS_MEDIA_TYPE_PLAIN</code>, or <code>CUPS_MEDIA_TYPE_TRANSPARENCY</code>.</li> + <li><code>CUPS_NUMBER_UP</code>: Controls the number of document pages that are placed on each media side.</li> + <li><code>CUPS_ORIENTATION</code>: Controls the orientation of document pages placed on the media: <code>CUPS_ORIENTATION_PORTRAIT</code> or <code>CUPS_ORIENTATION_LANDSCAPE</code>.</li> + <li><code>CUPS_PRINT_COLOR_MODE</code>: Controls whether the output is in color (<code>CUPS_PRINT_COLOR_MODE_COLOR</code>), grayscale (<code>CUPS_PRINT_COLOR_MODE_MONOCHROME</code>), or either (<code>CUPS_PRINT_COLOR_MODE_AUTO</code>).</li> + <li><code>CUPS_PRINT_QUALITY</code>: Controls the generate quality of the output: <code>CUPS_PRINT_QUALITY_DRAFT</code>, <code>CUPS_PRINT_QUALITY_NORMAL</code>, or <code>CUPS_PRINT_QUALITY_HIGH</code>.</li> + <li><code>CUPS_SIDES</code>: Controls whether prints are placed on one or both sides of the media: <code>CUPS_SIDES_ONE_SIDED</code>, <code>CUPS_SIDES_TWO_SIDED_PORTRAIT</code>, or <code>CUPS_SIDES_TWO_SIDED_LANDSCAPE</code>.</li> +</ul> + <p>If the <code>value</code> argument is <code>NULL</code>, the <code>cupsCheckDestSupported</code> function returns whether the option is supported by the destination. Otherwise, the function returns whether the specified value of the option is supported.</p> + <p>The <code>cupsFindDestSupported</code> function returns the IPP attribute containing the supported values for a given option:</p> + <pre><code> ipp_attribute_t * + cupsFindDestSupported(http_t *http, cups_dest_t *dest, + cups_dinfo_t *dinfo, + const char *option); +</code></pre> + <p>For example, the following code prints the supported finishing processes for a destination, if any, to the standard output:</p> + <pre><code>cups_dinfo_t *info = cupsCopyDestInfo(CUPS_HTTP_DEFAULT, + dest); + +if (cupsCheckDestSupported(CUPS_HTTP_DEFAULT, dest, info, + CUPS_FINISHINGS, NULL)) +{ + ipp_attribute_t *finishings = + cupsFindDestSupported(CUPS_HTTP_DEFAULT, dest, info, + CUPS_FINISHINGS); + int i, count = ippGetCount(finishings); + + puts("finishings supported:"); + for (i = 0; i < count; i ++) + printf(" %d\n", ippGetInteger(finishings, i)); +} +else + puts("finishings not supported."); +</code></pre> + <p>The "job-creation-attributes" option can be queried to get a list of supported options.

For example, the following code prints the default finishings value(s) to the standard output:</p> + <pre><code>const char *def_value = + cupsGetOption(CUPS_FINISHINGS, dest->num_options, + dest->options); +ipp_attribute_t *def_attr = + cupsFindDestDefault(CUPS_HTTP_DEFAULT, dest, info, + CUPS_FINISHINGS); + +if (def_value != NULL) +{ + printf("Default finishings: %s\n", def_value); +} +else +{ + int i, count = ippGetCount(def_attr); + + printf("Default finishings: %d", + ippGetInteger(def_attr, 0)); + for (i = 1; i < count; i ++) + printf(",%d", ippGetInteger(def_attr, i)); + putchar('\n'); +} +</code></pre> + <h4><a id="getting-ready-loaded-values">Getting Ready (Loaded) Values</a></h4> + <p>The finishings and media options also support queries for the ready, or loaded, values. For example, a printer may have punch and staple finishers installed but be out of staples - the supported values will list both punch and staple finishing processes but the ready values will only list the punch processes. Similarly, a printer may support hundreds of different sizes of media but only have a single size loaded at any given time - the ready values are limited to the media that is actually in the printer.</p> + <p>The <code>cupsFindDestReady</code> function finds the IPP attribute containing the ready values for a given option:</p> + <pre><code>ipp_attribute_t * +cupsFindDestReady(http_t *http, cups_dest_t *dest, + cups_dinfo_t *dinfo, const char *option); +</code></pre> + <p>For example, the following code lists the ready finishing processes:</p> + <pre><code>ipp_attribute_t *ready_finishings = + cupsFindDestReady(CUPS_HTTP_DEFAULT, dest, info, + CUPS_FINISHINGS); + +if (ready_finishings != NULL) +{ + int i, count = ippGetCount(ready_finishings); + + puts("finishings ready:"); + for (i = 0; i < count; i ++) + printf(" %d\n", ippGetInteger(ready_finishings, i)); +} +else + puts("no finishings are ready."); +</code></pre> + <h4><a id="media-size-options">Media Size Options</a></h4> + <p>CUPS provides functions for querying the dimensions and margins for each of the supported media size options. The <code>cups_size_t</code> structure is used to describe a media size:</p> + <pre><code>typedef struct cups_size_s +{ + char media[128]; + int width, length; + int bottom, left, right, top; +} cups_size_t; +</code></pre> + <p>The <code>width</code> and <code>length</code> members specify the dimensions of the media in hundredths of millimeters (1/2540th of an inch). The <code>bottom</code>, <code>left</code>, <code>right</code>, and <code>top</code> members specify the margins of the printable area, also in hundredths of millimeters.</p> + <p>The <code>cupsGetDestMediaByName</code> and <code>cupsGetDestMediaBySize</code> functions lookup the media size information using a standard media size name or dimensions in hundredths of millimeters:</p> + <pre><code>int +cupsGetDestMediaByName(http_t *http, cups_dest_t *dest, + cups_dinfo_t *dinfo, + const char *media, + unsigned flags, cups_size_t *size); + +int +cupsGetDestMediaBySize(http_t *http, cups_dest_t *dest, + cups_dinfo_t *dinfo, + int width, int length, + unsigned flags, cups_size_t *size); +</code></pre> + <p>The <code>media</code>, <code>width</code>, and <code>length</code> arguments specify the size to lookup. The <code>flags</code> argument specifies a bitfield controlling various lookup options:</p> + <ul> + <li><code>CUPS_MEDIA_FLAGS_DEFAULT</code>: Find the closest size supported by the printer.</li> + <li><code>CUPS_MEDIA_FLAGS_BORDERLESS</code>: Find a borderless size.</li> + <li><code>CUPS_MEDIA_FLAGS_DUPLEX</code>: Find a size compatible with two-sided printing.</li> + <li><code>CUPS_MEDIA_FLAGS_EXACT</code>: Find an exact match for the size.</li> + <li><code>CUPS_MEDIA_FLAGS_READY</code>: If the printer supports media sensing or configuration of the media in each tray/source, find the size amongst the "ready" media.</li> +</ul> + <p>If a matching size is found for the destination, the size information is stored in the structure pointed to by the <code>size</code> argument and 1 is returned.

The <code>cupsConnectDest</code> function connects to the scheduler or printer associated with the destination:</p> + <pre><code>http_t * +cupsConnectDest(cups_dest_t *dest, unsigned flags, int msec, + int *cancel, char *resource, + size_t resourcesize, cups_dest_cb_t cb, + void *user_data); +</code></pre> + <p>The <code>dest</code> argument specifies the destination to connect to.</p> + <p>The <code>flags</code> argument specifies whether you want to connect to the scheduler (<code>CUPS_DEST_FLAGS_NONE</code>) or device/printer (<code>CUPS_DEST_FLAGS_DEVICE</code>) associated with the destination.</p> + <p>The <code>msec</code> argument specifies how long you are willing to wait for the connection to be established in milliseconds. Specify a value of <code>-1</code> to wait indefinitely.</p> + <p>The <code>cancel</code> argument specifies the address of an integer variable that can be set to a non-zero value to cancel the connection. Specify a value of <code>NULL</code> to not provide a cancel variable.</p> + <p>The <code>resource</code> and <code>resourcesize</code> arguments specify the address and size of a character string array to hold the path to use when sending an IPP request.</p> + <p>The <code>cb</code> and <code>user_data</code> arguments specify a destination callback function that returns 1 to continue connecting or 0 to stop. The destination callback work the same way as the one used for the <code>cupsEnumDests</code> function.</p> + <p>On success, a HTTP connection is returned that can be used to send IPP requests and get IPP responses.</p> + <p>For example, the following code connects to the printer associated with a destination with a 30 second timeout:</p> + <pre><code>char resource[256]; +http_t *http = cupsConnectDest(dest, CUPS_DEST_FLAGS_DEVICE, + 30000, NULL, resource, + sizeof(resource), NULL, NULL); +</code></pre> + <h3><a id="creating-an-ipp-request">Creating an IPP Request</a></h3> + <p>IPP requests are represented by the IPP message type <code>ipp_t</code> and each IPP attribute in the request is representing using the type <code>ipp_attribute_t</code>. Each IPP request includes an operation code (<code>IPP_OP_CREATE_JOB</code>, <code>IPP_OP_GET_PRINTER_ATTRIBUTES</code>, etc.) and a 32-bit integer identifier.</p> + <p>The <code>ippNewRequest</code> function creates a new IPP request:</p> + <pre><code>ipp_t * +ippNewRequest(ipp_op_t op); +</code></pre> + <p>The <code>op</code> argument specifies the IPP operation code for the request. For example, the following code creates an IPP Get-Printer-Attributes request:</p> + <pre><code>ipp_t *request = ippNewRequest(IPP_OP_GET_PRINTER_ATTRIBUTES); +</code></pre> + <p>The request identifier is automatically set to a unique value for the current process.</p> + <p>Each IPP request starts with two IPP attributes, "attributes-charset" and "attributes-natural-language", followed by IPP attribute(s) that specify the target of the operation. The <code>ippNewRequest</code> automatically adds the correct "attributes-charset" and "attributes-natural-language" attributes, but you must add the target attribute(s). For example, the following code adds the "printer-uri" attribute to the IPP Get-Printer-Attributes request to specify which printer is being queried:</p> + <pre><code>const char *printer_uri = cupsGetOption("device-uri", + dest->num_options, + dest->options); + +ippAddString(request, IPP_TAG_OPERATION, IPP_TAG_URI, + "printer-uri", NULL, printer_uri); +</code></pre> + <blockquote> + <p>Note: If we wanted to query the scheduler instead of the device, we would look up the "printer-uri-supported" option instead of the "device-uri" value.</p> +</blockquote> + <p>The <code>ippAddString</code> function adds the "printer-uri" attribute the the IPP request. The <code>IPP_TAG_OPERATION</code> argument specifies that the attribute is part of the operation. The <code>IPP_TAG_URI</code> argument specifies that the value is a Universal Resource Identifier (URI) string. The <code>NULL</code> argument specifies there is no language (English, French, Japanese, etc.) associated with the string, and the <code>printer_uri</code> argument specifies the string value.</p> + <p>The IPP Get-Printer-Attributes request also supports an IPP attribute called "requested-attributes" that lists the attributes and values you are interested in. For example, the following code requests the printer state attributes:</p> + <pre><code>static const char * const requested_attributes[] = +{ + "printer-state", + "printer-state-message", + "printer-state-reasons" +}; + +ippAddStrings(request, IPP_TAG_OPERATION, IPP_TAG_KEYWORD, + "requested-attributes", 3, NULL, + requested_attributes); +</code></pre> + <p>The <code>ippAddStrings</code> function adds an attribute with one or more strings, in this case three. The <code>IPP_TAG_KEYWORD</code> argument specifies that the strings are keyword values, which are used for attribute names. All strings use the same language (<code>NULL</code>), and the attribute will contain the three strings in the array <code>requested_attributes</code>.</p> + <p>CUPS provides many functions to adding attributes of different types:</p> + <ul> + <li><code>ippAddBoolean</code> adds a boolean (<code>IPP_TAG_BOOLEAN</code>) attribute with one value.</li> + <li><code>ippAddInteger</code> adds an enum (<code>IPP_TAG_ENUM</code>) or integer (<code>IPP_TAG_INTEGER</code>) attribute with one value.</li> + <li><code>ippAddIntegers</code> adds an enum or integer attribute with one or more values.</li> + <li><code>ippAddOctetString</code> adds an octetString attribute with one value.</li> + <li><code>ippAddOutOfBand</code> adds a admin-defined (<code>IPP_TAG_ADMINDEFINE</code>), default (<code>IPP_TAG_DEFAULT</code>), delete-attribute (<code>IPP_TAG_DELETEATTR</code>), no-value (<code>IPP_TAG_NOVALUE</code>), not-settable (<code>IPP_TAG_NOTSETTABLE</code>), unknown (<code>IPP_TAG_UNKNOWN</code>), or unsupported (<code>IPP_TAG_UNSUPPORTED_VALUE</code>) out-of-band attribute.</li> + <li><code>ippAddRange</code> adds a rangeOfInteger attribute with one range.</li> + <li><code>ippAddRanges</code> adds a rangeOfInteger attribute with one or more ranges.</li> + <li><code>ippAddResolution</code> adds a resolution attribute with one resolution.</li> + <li><code>ippAddResolutions</code> adds a resolution attribute with one or more resolutions.</li> + <li><code>ippAddString</code> adds a charset (<code>IPP_TAG_CHARSET</code>), keyword (<code>IPP_TAG_KEYWORD</code>), mimeMediaType (<code>IPP_TAG_MIMETYPE</code>), name (<code>IPP_TAG_NAME</code> and <code>IPP_TAG_NAMELANG</code>), naturalLanguage (<code>IPP_TAG_NATURAL_LANGUAGE</code>), text (<code>IPP_TAG_TEXT</code> and <code>IPP_TAG_TEXTLANG</code>), uri (<code>IPP_TAG_URI</code>), or uriScheme (<code>IPP_TAG_URISCHEME</code>) attribute with one value.</li> + <li><code>ippAddStrings</code> adds a charset, keyword, mimeMediaType, name, naturalLanguage, text, uri, or uriScheme attribute with one or more values.</li> +</ul> + <h3><a id="sending-the-ipp-request">Sending the IPP Request</a></h3> + <p>Once you have created the IPP request, you can send it using the <code>cupsDoRequest</code> function.
