@var{errorDescription}: return the error description.
Creates the structures needed to manage the ASN.1 definitions.
@code{array} is a vector created by @code{asn1_parser2array()} .
@strong{Returns:} @code{ASN1_SUCCESS} if structure was created correctly,
@code{ASN1_ELEMENT_NOT_EMPTY} if * @code{definitions} not NULL,
@code{ASN1_IDENTIFIER_NOT_FOUND} if in the file there is an identifier
that is not defined (see @code{errorDescription} for more information),
@code{ASN1_ARRAY_ERROR} if the array pointed by @code{array} is wrong.

@var{structure}: pointer to the structure that you want to delete.
@var{flags}: additional flags (see @code{ASN1_DELETE_FLAG_ZEROIZE} )
Deletes the structure * @code{structure} . At the end, * @code{structure} is set
to NULL.
@strong{Returns:} @code{ASN1_SUCCESS} if successful, @code{ASN1_ELEMENT_NOT_FOUND} if
* @code{structure} was NULL.
@end deftypefun

@var{structure}: pointer to the structure that contains the element you
want to delete.
@var{element_name}: element's name you want to delete.
Deletes the element named * @code{element_name} inside * @code{structure} .
@strong{Returns:} @code{ASN1_SUCCESS} if successful, @code{ASN1_ELEMENT_NOT_FOUND} if
the @code{element_name} was not found.
@end deftypefun
@subheading asn1_create_element
@anchor{asn1_create_element}
@deftypefun {int} {asn1_create_element} (asn1_node_const @var{definitions}, const char * @var{source_name}, asn1_node * @var{element})
@var{definitions}: pointer to the structure returned by "parser_asn1" function
@var{source_name}: the name of the type of the new structure (must be
inside p_structure).
@var{element}: pointer to the structure created.
Creates a structure of type @code{source_name} . Example using
"pkix.asn":
rc = asn1_create_element(cert_def, "PKIX1.Certificate", certptr);
@strong{Returns:} @code{ASN1_SUCCESS} if creation OK, @code{ASN1_ELEMENT_NOT_FOUND} if
@code{source_name} is not known.
@end deftypefun
@subheading asn1_print_structure
@anchor{asn1_print_structure}
@deftypefun {void} {asn1_print_structure} (FILE * @var{out}, asn1_node_const @var{structure}, const char * @var{name}, int @var{mode})
@var{out}: pointer to the output file (e.g. stdout).
@var{structure}: pointer to the structure that you want to visit.
@var{name}: an element of the structure
@var{mode}: specify how much of the structure to print, can be
@code{ASN1_PRINT_NAME} , @code{ASN1_PRINT_NAME_TYPE} ,
@code{ASN1_PRINT_NAME_TYPE_VALUE} , or @code{ASN1_PRINT_ALL} .
Prints on the @code{out} file descriptor the structure's tree starting
from the @code{name} element inside the structure @code{structure} .
@end deftypefun
@subheading asn1_number_of_elements
@anchor{asn1_number_of_elements}
@deftypefun {int} {asn1_number_of_elements} (asn1_node_const @var{element}, const char * @var{name}, int * @var{num})
@var{element}: pointer to the root of an ASN1 structure.
@var{name}: the name of a sub-structure of ROOT.
@var{num}: pointer to an integer where the result will be stored
Counts the number of elements of a sub-structure called NAME with
names equal to "?1","?2", ...
@strong{Returns:} @code{ASN1_SUCCESS} if successful, @code{ASN1_ELEMENT_NOT_FOUND} if
@code{name} is not known, @code{ASN1_GENERIC_ERROR} if pointer @code{num} is @code{NULL} .

constant string that contains the element name defined just after
the OID.
