The callback function must use the Pascal calling convention, must be exported with __export, and must be declared FAR.
short FAR PASCAL __export AbortFunc( HDC hPr, short code );
The name AbortFunc is a placeholder for the application-supplied function name. The actual name must be exported as described in the “Remarks” section above.
| Parameter | Description |
| hPr | Identifies the device context. |
| code | Specifies whether an error has occurred. It is 0 if no error has occurred. It is SP_OUTOFDISK if Print Manager is currently out of disk space and more disk space will become available if the application waits. If code is SP_OUTOFDISK, the application does not have to abort the print job. If it does not, it must yield to Print Manager by calling the PeekMessage or GetMessage function. |
Return Value
The return value of the abort-handler function is nonzero if the print job is to continue, and 0 if it is canceled.
