XdbeQueryExtension(3X11)   X FUNCTIONS	XdbeQueryExtension(3X11)

NAME
       XdbeQueryExtension  - returns the version of DBE supported
       by the server.

SYNOPSIS
       #include <X11/extensions/Xdbe.h>

       Status XdbeQueryExtension(
	   Display *dpy,
	   int	*major_version_return,
	   int	*minor_version_return)

DESCRIPTION
       Sets major_version_return and minor_version_return to  the
       major  and  minor  DBE  protocol version supported by the
       server.	If the DBE library is compatible with the version
       returned by  the	 server, this function returns non-zero.
       If dpy does not support the DBE extension, or if there was
       an  error  during communication with the server, or if the
       server and library  protocol  versions  are  incompatible,
       this  function  returns zero.  No other Xdbe functions may
       be called before this function.	If a client violates this
       rule,  the  effects  of	all subsequent Xdbe calls that it
       makes are undefined.
