Expand description

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.)


the required major version


the required minor version


the required micro version


None 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.
