Description [src]

Checks that the GLib library in use is compatible with the given version.

Generally you would pass in the constants 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.).

Available since: 2.6
