XPRINT FUNCTIONS                            XpQueryExtension(3Xp)



NAME
     XpQueryExtension - Queries an X Server to  determine  if  it
     supports the X Print Service Extension, and if it does, what
     the offsets are for associated events and errors.

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

     Bool   XpQueryExtension   (    display,    event_base_return
     error_base_return )
           Display *display;
           int *event_base_return;
           int *error_base_return;

ARGUMENTS
     display
          Specifies a pointer to the Display structure;  returned
          from XOpenDisplay.

     event_base_return
          The base value for X Print Service Extension events

     error_base_return
          The base value for X Print Service Extension errors.

DESCRIPTION
     XpQueryExtension determines if the X Print Service Extension
     is  present.  It returns True if the extension is supported,
     otherwise False. If  the  extension  is  present,  the  base
     values  for  events and errors are returned, and can be used
     to decode incoming event and error values.

     The X Print Service Extension is initialized  on  the  first
     call  to  any  X Print Service function; there is no need to
     explicitly initialize the X Print Service Extension.
