XpQueryExtension(3Xp) XPRINT FUNCTIONS XpQueryExtension(3Xp)
NAME
XpQueryExtension - Queries an X Server to determine if it supports the
X Print Service Extension, and if it does, what the offsets are for
associated events and errors.
SYNOPSIS
cc [ flag... ] file... -lXp [ library... ]
#include <X11/extensions/Print.h>
Bool XpQueryExtension ( display, event_base_return error_base_return )
Display *display;
int *event_base_return;
int *error_base_return;
ARGUMENTS
display
Specifies a pointer to the Display structure; returned from
XOpenDisplay.
event_base_return
The base value for X Print Service Extension events
error_base_return
The base value for X Print Service Extension errors.
DESCRIPTION
XpQueryExtension determines if the X Print Service Extension is
present. It returns True if the extension is supported, otherwise
False. If the extension is present, the base values for events and
errors are returned, and can be used to decode incoming event and error
values.
The X Print Service Extension is initialized on the first call to any X
Print Service function; there is no need to explicitly initialize the X
Print Service Extension.
