XkbLibraryVersion - Determines the compatibility of a library at runtime.
Bool XkbLibraryVersion (int
- Specifies and returns the major Xkb library version.
- Specifies and returns the minor Xkb library version.
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 lib_major_in_out
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.
versions of the compile time and run time libraries are compatible,
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.
- The XkbLibraryVersion returns True if the versions of the compile
time and run time libraries are compatible.
- The XkbLibraryVersion returns False if the versions of the compile
time and run time libraries are not compatible.
