+.SH DESCRIPTION
+.LP
+As a convenience, you can use the function
+.I XkbOpenDisplay
+to perform these three
+tasks at once: open a connection to an X server, check for a compatible version
+of the Xkb extension in both the library and the server, and initialize the
+extension for use.
+
+.I XkbOpenDisplay
+is a convenience function that opens an X display connection and
+initializes the X keyboard extension. In all cases, upon return
+.I reason_rtrn
+contains a status value indicating success or the type of failure. If
+.I major_in_out
+and
+.I minor_in_out
+are not NULL,
+.I XkbOpenDisplay
+first calls
+.I XkbLibraryVersion
+to determine whether the client library is compatible, passing
+it the values pointed to by
+.I major_in_out and
+.I minor_in_out. If the library is
+incompatible,
+.I XkbOpenDisplay backfills
+.I major_in_out
+and
+.I minor_in_out
+with the
+major and minor extension versions of the library being used and returns NULL.
+If the library is compatible,
+.I XkbOpenDisplay
+next calls
+.I XOpenDisplay
+with the
+.I display_name.
+If this fails, the function returns NULL. If successful,
+.I XkbOpenDisplay
+calls
+.I XkbQueryExtension
+and backfills the major and minor Xkb
+server extension version numbers in
+.I major_in_out and
+.I minor_in_out. If the server
+extension version is not compatible with the library extension version or if the
+server extension is not present,
+.I XkbOpenDisplay
+closes the display and returns
+NULL. When successful, the function returns the display connection.
+
+The possible values for reason_rtrn are:
+
+.IP \(bu 5
+XkbOD_BadLibraryVersion indicates XkbLibraryVersion returned False.
+.IP \(bu 5
+XkbOD_ConnectionRefused indicates the display could not be opened.
+.IP \(bu 5
+XkbOD_BadServerVersion indicates the library and the server have incompatible
+extension versions.
+.IP \(bu 5
+XkbOD_NonXkbServer indicates the extension is not present in the X server.
+.IP \(bu 5
+XkbOD_Success indicates that the function succeeded.
+.SH "RETURN VALUES"
+.TP 15

+The
+.I XkbOpenDisplay
+function returns NULL if the library is incompatible.

+The

+function returns NULL and closes the display if the server extension version is not
