XdbeQueryExtension(3)                            X FUNCTIONS                           XdbeQueryExtension(3)



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 sup-ported supported
       ported 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 dur-ing during
       ing 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.
