A fax client application calls the FaxSetJob function to pause, resume, cancel, or restart a specified fax job.

Syntax

WINFAXAPI BOOL FaxSetJobA(
  [in] HANDLE               FaxHandle,
  [in] DWORD                JobId,
  [in] DWORD                Command,
  [in] const FAX_JOB_ENTRYA *JobEntry
);

Parameters

[in] FaxHandle

Type: HANDLE

Specifies a fax server handle returned by a call to the FaxConnectFaxServer function.

[in] JobId

Type: DWORD

Specifies a DWORD variable that is a unique number to identify the fax job to modify. Call the FaxEnumJobs function to retrieve a valid fax job identifier to use in the JobId parameter.

[in] Command

Type: DWORD

Specifies a DWORD variable that indicates the job command to perform. This parameter can be one of the following values.

JC_DELETE

Cancel the specified fax job. The job can be active or queued.

JC_PAUSE

Pause the specified queued fax job. If the fax job is active, the fax service pauses the job when it returns to the queued state.

JC_RESUME

Resume the paused fax job.

JC_RESTART

Restart the specified fax job.

[in] JobEntry

Type: const FAX_JOB_ENTRY*

Not used, must be NULL.

Return value

Type: BOOL

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError. GetLastError can return one of the following errors.

Return code	Description
ERROR_ACCESS_DENIED	Access is denied. FAX_JOB_MANAGE access is required.
ERROR_INVALID_PARAMETER	The FaxHandle parameter is NULL, or one or all of the Command, JobEntry, or JobId parameters are invalid.

Remarks

An application typically calls the FaxSetJob function to manage a queued fax job. To terminate a fax transmission that is in progress, an application can call the FaxAbort function.

Note

The winfax.h header defines FaxSetJob as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
