.SH NAME
XpCancelPage \- Cancels a print page.

.SH ARGUMENTS
.TP
.I display
Specifies a pointer to the Display structure; returned from XOpenDisplay.
.TP
.I discard
When TRUE, specifies that XPPrintNotify events with a detail of XPEndPageNotify 
should be discarded.
.SH DESCRIPTION
.LP
XpCancelPage cancels an in-progress print page. If the job was started with 
output_mode XPGetData then the data stream to XpGetDocumentData is interrupted; 
no 
further data for the current page is generated but data for subsequent pages can 
be generated. For many page description languages, such arbitrary interruptions 
may invalidate the output.

If the job was started with output_mode XPSpool then depending on the driver and 
spooler implementation the 
entire page may be canceled or a partial page may be generated.

If 
.I discard 
is True all XPPrintNotify events with a detail field of XPEndPageNotify 
are discarded before XpCancelPage returns.

For clients selecting XPPrintMask (see XpSelectInput), the event XPPrintNotify 
is 
generated with its detail field set to XPEndPageNotify when the X Print Server 
has 
completed XpCancelPage. 
.SH DIAGNOSTICS
.TP 15
.SM XPBadSequence
The function was not called in the proper order with respect to the 
other X Print Service Extension calls; for example, XpStartPage was 
called before XpStartJob or was called for a type XPDocRaw document.
