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; other-
       wise 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.
