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 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.
