## Includes

    #include <gdk-pixbuf/gdk-pixbuf.h>

## Description

These macros and variables let you check the version of gdk-pixbuf you're linking against.

## Functions

### GDK_PIXBUF_CHECK_VERSION()

    #define             GDK_PIXBUF_CHECK_VERSION(major, minor, micro)

Macro to test the version of GdkPixbuf being compiled against.

#### Parameters

major | major version (e.g. 2 for version 2.34.0) |
minor | minor version (e.g. 34 for version 2.34.0) |
micro | micro version (e.g. 0 for version 2.34.0) |

#### Returns

`TRUE` if the version of the GdkPixbuf header files is the same as or newer than the passed-in version.

Since: 2.36

## Types and Values

### gdk_pixbuf_version

    extern const char *gdk_pixbuf_version;

Contains the full version of the gdk-pixbuf library as a string. This is the version currently in use by a running program.

### gdk_pixbuf_major_version

    extern const guint gdk_pixbuf_major_version;

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

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MAJOR macro, which represents the major version of the gdk-pixbuf headers you have included.

### gdk_pixbuf_minor_version

    extern const guint gdk_pixbuf_minor_version;

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

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MINOR macro, which represents the minor version of the gdk-pixbuf headers you have included.

### gdk_pixbuf_micro_version

    extern const guint gdk_pixbuf_micro_version;

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

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MICRO macro, which represents the micro version of the gdk-pixbuf headers you have included.

### GDK_PIXBUF_VERSION

    #define GDK_PIXBUF_VERSION "2.40.1"

    #define GDK_PIXBUF_VERSION_MIN_REQUIRED (GDK_PIXBUF_VERSION_CUR_STABLE)

This macro defines the lower bound for the GdkPixbuf API to use.

If a function has been deprecated in a newer version of GdkPixbuf, defining this symbol hides the compiler warnings for those functions without disabling warnings for the other deprecated functions.

Warning: if you define this macro, do not forget to update it! Especially when writing new code. Otherwise you can miss the new deprecations.

This macro defines the upper bound for the GdkPixbuf API to use.

If a function has been introduced in a newer version of GdkPixbuf, it is possible to use this symbol to get compiler warnings when trying to use that function.
