XpQueryScreens(3Xp) XPRINT FUNCTIONS XpQueryScreens(3Xp)
NAME
XpQueryScreens - 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 sin-gle single
gle 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.
