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 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.
