Applications will not typically use the features described here. Detailsgtk_major_versionextern const guint gtk_major_version; The major version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 1.) This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MAJOR_VERSION macro, which represents the major version of the GTK+ headers you have included. gtk_minor_versionextern const guint gtk_minor_version; The minor version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 2.) This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MINOR_VERSION macro, which represents the minor version of the GTK+ headers you have included. gtk_micro_versionextern const guint gtk_micro_version; The micro version number of the GTK+ library. (e.g. in GTK+ version 1.2.5 this is 5.) This variable is in the library, so represents the GTK+ library you have linked against. Contrast with the GTK_MICRO_VERSION macro, which represents the micro version of the GTK+ headers you have included. gtk_binary_ageextern const guint gtk_binary_age; This is the binary age passed to libtool. If libtool means nothing to you, don't worry about it. ;-) gtk_interface_ageextern const guint gtk_interface_age; This is the interface age passed to libtool. If libtool means nothing to you, don't worry about it. ;-) gtk_check_version ()const gchar* gtk_check_version (guint required_major, guint required_minor, guint required_micro); Checks that the GTK+ library in use is compatible with the given version. Generally you would pass in the constants GTK_MAJOR_VERSION, GTK_MINOR_VERSION, GTK_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of GTK+ 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
This function is primarily for GTK+ modules; the module
can call this function to check that it wasn't loaded
into an incompatible version of GTK+. However, such a
a check isn't completely reliable, since the module may be
linked against an old version of GTK+ and calling the
old version of
