XKB FUNCTIONS                             XkbLibraryVersion(3x11)



NAME
     XkbLibraryVersion  -   Determines  the  compatibility  of  a
     library at runtime.

SYNOPSIS
     cc [ flag... ] file... -lX11 [ library... ]

     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  capabili-
     ties.  Therefore a dynamically linked application must check
     both the library and the  server  for  compatibility  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 compa-
     tibility. (It is possible to  compile  against  one  set  of
     header  files  and  link  against a different, incompatible,
     version of the library, although this  should  not  normally
     occur.)

     Pass the symbolic value XkbMajorVersion in  lib_major_in_out
     and  XkbMinorVersion  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,
     XkbLibraryVersion 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 compatible.
