Obtaining a Fax Status
The fax service calls the FaxDevReportStatus function asynchronously to query a fax service provider (FSP) DLL about status information for an active fax operation, or for status information after a failed fax operation. The service also calls FaxDevReportStatus synchronously at the end of each job. The FAX_DEVICE_STATUS structure contains a status error code, a Microsoft Win32 error code, and routing information for the fax operation.
The FSP must export the FaxDevReportStatus function.
