* glib_check_version:

* Checks that the GLib library in use is compatible with the

* #GLIB_MAJOR_VERSION, #GLIB_MINOR_VERSION, #GLIB_MICRO_VERSION
* as the three arguments to this function; that produces
* a check that the library in use is compatible with
* the version of GLib the application or module was compiled
* against.
*
* Compatibility is defined by two things: first the version
* of the running library is newer than the version
* @required_major.required_minor.@required_micro. Second
* the running library must be binary compatible with the
* version @required_major.required_minor.@required_micro
* (same major version.)
*
* Return value: %NULL if the GLib library is compatible with the
* given version, or a string describing the version mismatch.
* The returned string is owned by GLib and must not be modified
* or freed.
