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. +.SH "SEE ALSO" +.BR XkbMajorVersion (__libmansuffix__), +.BR XkbMinorVersion (__libmansuffix__), +.BR XkbQueryExtension (__libmansuffix__) |
