XdbeQueryExtension(3X1Version 11 (ReleaseXdbeQueryExtension(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.
