ABORTPROC callback function (wingdi.h)

The AbortProc function is an application-defined callback function used with the SetAbortProc function. It is called when a print job is to be canceled during spooling. The ABORTPROC type defines a pointer to this callback function. AbortProc is a placeholder for the application-defined function name.

Syntax

ABORTPROC Abortproc;

BOOL Abortproc(
  HDC unnamedParam1,
  int unnamedParam2
)
{...}

Parameters

unnamedParam1

unnamedParam2

Return value

The callback function should return TRUE to continue the print job or FALSE to cancel the print job.

Remarks

Note  This is a blocking or synchronous function and might not return immediately. How quickly this function returns depends on run-time factors such as network status, print server configuration, and printer driver implementation—factors that are difficult to predict when writing an application. Calling this function from a thread that manages interaction with the user interface could make the application appear to be unresponsive.

 

If the iError parameter is SP_OUTOFDISK, the application need not cancel the print job. If it does not cancel the job, it must yield to Print Manager by calling the PeekMessage or GetMessage function.
