XkbLibraryVersion(3)		 XKB FUNCTIONS		  XkbLibraryVersion(3)

NAME
       XkbLibraryVersion  -  Determines	the compatibility of a library at run-
       time.

SYNOPSIS
       Bool XkbLibraryVersion (int *lib_major_in_out, int *lib_minor_in_out);

ARGUMENTS
       lib_major_in_out
	      Specifies	and returns the	major Xkb library version.

       lib_minor_in_out
	      Specifies	and returns the	minor Xkb library version.

DESCRIPTION
       If an application is dynamically	linked,	both  the  X  server  and  the
       client-side  X  library must contain the	Xkb extension in order for the
       client to use the Xkb extension capabilities. Therefore	a  dynamically
       linked  application must	check both the library and the server for com-
       patibility before using Xkb function calls. A properly written  program
       must  check  for	 compatibility	between	the version of the Xkb library
       that is dynamically loaded and the one used when	 the  application  was
       built. It must then check the server version for	compatibility with the
       version of Xkb in the library.

       If your application is statically linked,  you  must  still  check  for
       server compatibility and	may check library compatibility. (It is	possi-
       ble to compile against one set of header	files and link against a  dif-
       ferent,	incompatible, version of the library, although this should not
       normally	occur.)

       Pass the	symbolic value XkbMajorVersion in lib_major_in_out and	XkbMi-
       norVersion  in lib_minor_in_out.	 These arguments represent the version
       of the library used at compile  time.  The  XkbLibraryVersion  function
       backfills  the  major  and minor	version	numbers	of the library used at
       run time	in lib_major_in_out and	lib_minor_in_out.  If the versions  of
       the  compile time and run time libraries	are compatible,	XkbLibraryVer-
       sion returns True, otherwise, it	returns	False.

       In addition, in order to	use the	Xkb extension, you  must  ensure  that
       the extension is	present	in the server and that the server supports the
       version of the extension	expected by the	client.	Use  XkbQueryExtension
       to do this, as described	in the next section.

RETURN VALUES
       True	      The  XkbLibraryVersion  returns  True if the versions of
		      the compile time and run time libraries are compatible.

       False	      The XkbLibraryVersion returns False if the  versions  of
		      the compile time and run time libraries are not compati-
		      ble.
