# Version Information

## Name

Version Information -- variables and functions to check the GTK+ version.

## Synopsis

    #include <gtk/gtk.h>

    extern      const guint gtk_major_version;
    extern      const guint gtk_minor_version;
    extern      const guint gtk_micro_version;
    extern      const guint gtk_binary_age;
    extern      const guint gtk_interface_age;

                                                 guint required_minor,
                                                 guint required_micro);

## Description

This section describes the variables and functions available to test the version of the GTK+ library in use. FIXME: probably merge with other general stuff.

## Details

### gtk_major_version

    extern const guint gtk_major_version;

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

### gtk_minor_version

    extern const guint gtk_minor_version;

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

### gtk_micro_version

    extern const guint gtk_micro_version;

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

### gtk_binary_age

    extern const guint gtk_binary_age;

### gtk_interface_age

    extern const guint gtk_interface_age;

### gtk_check_version ()

    gchar*      gtk_check_version               (guint required_major,
                                                 guint required_minor,
                                                 guint required_micro);

Checks that the GTK+ library in use is compatable with the given version.

`required_major` : | the required major version.
`required_minor` : | the required major version.
`required_micro` : | the required major version.
Returns : | NULL if the GTK+ library is compatable with the given version, or a string describing the version mismatch.
