glib_major_version

extern const guint glib_major_version;

The major version number of the GLib library. (e.g. in GLib version 1.2.5 this is 1.)

This variable is in the library, so represents the GLib library you have linked against. Contrast with the GLIB_MAJOR_VERSION macro, which represents the major version of the GLib headers you have included.

glib_minor_version

extern const guint glib_minor_version;

The minor version number of the GLib library. (e.g. in GLib version 1.2.5 this is 2.)

This variable is in the library, so represents the GLib library you have linked against. Contrast with the GLIB_MINOR_VERSION macro, which represents the minor version of the GLib headers you have included.

glib_micro_version

extern const guint glib_micro_version;

The micro version number of the GLib library. (e.g. in GLib version 1.2.5 this is 5.)

This variable is in the library, so represents the GLib library you have linked against. Contrast with the GLIB_MICRO_VERSION macro, which represents the micro version of the GLib headers you have included.

glib_binary_age

extern const guint glib_binary_age;

This is the binary age passed to libtool. If libtool means nothing to you, don't worry about it. ;-)

glib_interface_age

extern const guint glib_interface_age;

This is the interface age passed to libtool. If libtool means nothing to you, don't worry about it. ;-)

glib_check_version ()

const gchar* glib_check_version             (guint required_major,
                                             guint required_minor,
                                             guint required_micro);

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.)

Since 2.6

GLIB_MAJOR_VERSION

#define GLIB_MAJOR_VERSION 2

The major version number of the GLib library. Like glib_major_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

GLIB_MINOR_VERSION

#define GLIB_MINOR_VERSION 6

The minor version number of the GLib library. Like gtk_minor_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

GLIB_MICRO_VERSION

#define GLIB_MICRO_VERSION 5

The micro version number of the GLib library. Like gtk_micro_version, but from the headers used at application compile time, rather than from the library linked against at application run time.

GLIB_CHECK_VERSION()

#define     GLIB_CHECK_VERSION(major,minor,micro)

Checks the version of the GLib library. Returns TRUE if the version of the GLib header files is the same as or newer than the passed-in version.

  if (!GLIB_CHECK_VERSION (1, 2, 0))
    g_error ("GLib version 1.2.0 or above is needed");
