Function:
  SetErrorMode

The SetErrorMode function controls whether the system will handle the
specified types of serious errors, or whether the process will handle
them.

Parameters

uMode
       [in] Specifies the process error mode. This parameter can be one or more of the following values. 

        Value                     Action
        0                         Use the system default, which is to display all error dialog boxes.
        SEM_FAILCRITICALERRORS    The system does not display the critical-error-handler message box. Instead,
                                  the system sends the error to the calling process.
        SEM_NOOPENFILEERRORBOX    The system does not display a message box when it fails to find a file. Instead,
                                  the error is returned to the calling process.

Return Values

The return value is the previous state of the error-mode bit flags.

/*++
Function:
  GetLastError

GetLastError

The GetLastError function retrieves the calling thread's last-error
code value. The last-error code is maintained on a per-thread
basis. Multiple threads do not overwrite each other's last-error code.

Parameters

This function has no parameters.

Return Values

The return value is the calling thread's last-error code
value. Functions set this value by calling the SetLastError
function. The Return Value section of each reference page notes the
conditions under which the function sets the last-error code.

/*++
Function:
  SetLastError

SetLastError

The SetLastError function sets the last-error code for the calling thread.

Parameters

dwErrCode
       [in] Specifies the last-error code for the thread.

Return Values

This function does not return a value.
