+.SH DESCRIPTION
+.LP
+Call
+.I XkbQueryExtension
+to check for the presence and compatibility of the
+extension in the server and to initialize the extension. Because of potential
+version mismatches, you cannot use the generic extension mechanism functions
+(
+.I XQueryExtension
+and
+.I XInitExtension
+) for checking for the presence of, and
+initializing the Xkb extension.
+
+You must call
+.I XkbQueryExtension
+or
+.I XkbOpenDisplay
+before using any other Xkb
+library interfaces, unless such usage is explicitly allowed in the interface
+description in this document. The exceptions are:
+.I XkbIgnoreExtension, XkbLibraryVersion,
+and a handful of audible-bell functions. You should not use
+any other Xkb functions if the extension is not present or is uninitialized. In
+general, calls to Xkb library functions made prior to initializing the Xkb
+extension cause BadAccess protocol errors.
+
+.I XkbQueryExtension
+both determines whether a compatible Xkb extension is present
+in the X server and initializes the extension when it is present.
+
+The
+.I XkbQueryExtension
+function determines whether a compatible version of the X
+Keyboard Extension is present in the server. If a compatible extension is
+present,
+.I XkbQueryExtension
+returns True; otherwise, it returns False.
+
+If a compatible version of Xkb is present,
+.I XkbQueryExtension
+initializes the
+extension. It backfills the major opcode for the keyboard extension in
+.I opcode_rtrn,
+the base event code in
+.I event_rtrn,
+the base error code in
+.I error_rtrn,
+and the major and minor version numbers of the extension in
+.I major_in_out
+and
+.I minor_in_out.
+The major opcode is reported in the
+.I req_major
+fields of some Xkb events. For a discussion of the base event code.
+.SH "RETURN VALUES"
+.TP 15
+True
+The
+.I XkbQueryExtension
+function returns True if it determines a compatible version of the X
+Keyboard Extension is present in the server.
+.TP 15
+False
+The
+.I XkbQueryExtension
+function returns False if it determines a compatible version of the X
+Keyboard Extension is not present in the server.
