XpQueryScreens(3)

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.
