gtk_get_major_version ()

guint               gtk_get_major_version               (void);

Returns the major version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 3.)

This function is in the library, so it represents the GTK+ library your code is running against. Contrast with the GTK_MAJOR_VERSION macro, which represents the major version of the GTK+ headers you have included when compiling your code.

Since 3.0

gtk_get_minor_version ()

guint               gtk_get_minor_version               (void);

Returns the minor version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 1.)

This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with the GTK_MINOR_VERSION macro, which represents the minor version of the GTK+ headers you have included when compiling your code.

Since 3.0

gtk_get_micro_version ()

guint               gtk_get_micro_version               (void);

Returns the micro version number of the GTK+ library. (e.g. in GTK+ version 3.1.5 this is 5.)

This function is in the library, so it represents the GTK+ library your code is are running against. Contrast with the GTK_MICRO_VERSION macro, which represents the micro version of the GTK+ headers you have included when compiling your code.

Since 3.0

gtk_get_binary_age ()

guint               gtk_get_binary_age                  (void);

Returns the binary age as passed to libtool when building the GTK+ library the process is running against. If libtool means nothing to you, don't worry about it.

Since 3.0

gtk_get_interface_age ()

guint               gtk_get_interface_age               (void);

Returns the interface age as passed to libtool when building the GTK+ library the process is running against. If libtool means nothing to you, don't worry about it.

Since 3.0

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 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.)

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 check isn't completely reliable, since the module may be linked against an old version of GTK+ and calling the old version of gtk_check_version(), but still get loaded into an application using a newer version of GTK+.

GTK_MAJOR_VERSION

#define GTK_MAJOR_VERSION (3)

Like gtk_get_major_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

GTK_MINOR_VERSION

#define GTK_MINOR_VERSION (0)

Like gtk_get_minor_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

GTK_MICRO_VERSION

#define GTK_MICRO_VERSION (3)

Like gtk_get_micro_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

GTK_BINARY_AGE

#define GTK_BINARY_AGE    (3)

Like gtk_get_binary_age(), but from the headers used at application compile time, rather than from the library linked against at application run time.

GTK_INTERFACE_AGE

#define GTK_INTERFACE_AGE (3)

Like gtk_get_interface_age(), but from the headers used at application compile time, rather than from the library linked against at application run time.
