+.SH NAME
+XkbLibraryVersion \-  Determines the compatibility of a library at runtime.
+.SH SYNOPSIS
+.B Bool XkbLibraryVersion
+(
+.I lib_major_in_out,
+.I lib_minor_in_out
+)
+.br
+      int *\fIlib_major_in_out\fP\^;
+.br
+      int *\fIlib_minor_in_out\fP\^;
+.if n .ti +5n
+.if t .ti +.5i
+.SH ARGUMENTS
+.TP
+.I lib_major_in_out
+Specifies and returns the major Xkb library version.
+.TP
+.I lib_minor_in_out
+Specifies and returns the minor Xkb library version.
+.SH DESCRIPTION
+.LP
+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 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 compatibility. (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 
+.I lib_major_in_out 
+and XkbMinorVersion in 
+.I lib_minor_in_out. 
+These arguments represent the version of the library used 
+at compile time. The 
+.I XkbLibraryVersion 
+function backfills the major and minor version numbers of the library used at 
+run time in 
+.I lib_major_in_out and 
+.I lib_minor_in_out. 
+If the versions of the compile time and run time libraries are 
+compatible, 
+.I 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 
+.I XkbQueryExtension 
+to do this, as described in the next section.
+.SH "RETURN VALUES"
+.TP 15
+True
+The 
+.I XkbLibraryVersion 
+returns True if the versions of the compile time and run time libraries are 
+compatible.
+.TP 15
+False
+The 
+.I XkbLibraryVersion 
+returns False if the versions of the compile time and run time libraries are not 
+compatible.
