.TH XdbeQueryExtension __libmansuffix__ __xorgversion__ "X FUNCTIONS"
|
|
.SH NAME
|
|
XdbeQueryExtension - returns the version of DBE supported by the server.
|
|
.SH SYNOPSIS
|
|
\&#include <X11/extensions/Xdbe.h>
|
|
|
|
Status XdbeQueryExtension(
|
|
Display *dpy,
|
|
int *major_version_return,
|
|
int *minor_version_return)
|
|
.SH DESCRIPTION
|
|
Sets
|
|
.I major_version_return
|
|
and
|
|
.I 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
|
|
.I 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.
