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... ]
           cc [ flag... ] file... -lXp [ library... ]
           #include 

     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 res-
     tricted 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.
