XpQueryScreens(3Xp) X Version 11 XpQueryScreens(3Xp)NAMEXpQueryScreens - Queries an X Server to determine which screens, of all
the screens on the server, support the X Print Service Extension
SYNOPSIS
cc [ flag... ] file... -lXp [ library... ]
#include <X11/extensions/Print.h>
Screen **XpQueryScreens ( display, list_count_return )
Display *display;
int *list_count_return;
ARGUMENTS
display
Specifies a pointer to the Display structure; returned from
XOpenDisplay.
list_count_return
Returns the number of screens in the list.
DESCRIPTION
This request returns a non-NULL pointer to a list of screen pointers if
one or more screens support the X Print Service Extension; otherwise it
returns NULL.
XpQueryScreens determines if the X Print Service Extension is present,
and if so, which of all the screens on the X Server support the X Print
Service Extension. Unlike many other extensions, the X Print Service
Extension may be restricted to a subset of all available screens - for
example, a single X Server may be supporting video displays on some
screens and printers on others.
The list of screen pointers can be freed by calling XFree.
