LIBFO_VERSION_ENCODE()

#define             LIBFO_VERSION_ENCODE(major, minor, micro)

This macro encodes the given libfo version into an integer. The numbers returned by LIBFO_VERSION and libfo_version() are encoded using this macro. Two encoded version numbers can be compared as integers.

LIBFO_VERSION_CHECK()

#define             LIBFO_VERSION_CHECK(major,minor,micro)

Checks that the version of libfo available at compile-time is not older than the provided version number.

libfo_version ()

int
libfo_version (void);

This is similar to the macro LIBFO_VERSION except that it returns the encoded version of libfo available at run-time, as opposed to the version available at compile-time.

A version number can be encoded into an integer using LIBFO_VERSION_ENCODE().

libfo_version_string ()

const char *
libfo_version_string (void);

This is similar to the macro LIBFO_VERSION_STRING except that it returns the version of libfo available at run-time, as opposed to the version available at compile-time.

libfo_version_check ()

const char *
libfo_version_check (int required_major,
                     int required_minor,
                     int required_micro);

Checks that the libfo library in use is compatible with the given version. Generally you would pass in the constants LIBFO_VERSION_MAJOR, LIBFO_VERSION_MINOR, LIBFO_VERSION_MICRO as the three arguments to this function; that produces a check that the library in use at run-time is compatible with the version of libfo 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.)

For compile-time version checking use LIBFO_VERSION_CHECK().

libfo_pixels_per_inch ()

int
libfo_pixels_per_inch (void);

This is similar to the macro LIBFO_PIXELS_PER_INCH except that it returns the encoded pixels per inch of libfo available at run-time, as opposed to the pixels per inch available at compile-time.

libfo_version_get_info ()

const LibfoVersionInfo **
libfo_version_get_info (void);

Gets the LibfoVersionInfo of libfo components.

LIBFO_VERSION_MAJOR

#define LIBFO_VERSION_MAJOR 0

The major component of the version of libfo available at compile-time.

LIBFO_VERSION_MINOR

#define LIBFO_VERSION_MINOR 6

The minor component of the version of libfo available at compile-time.

LIBFO_VERSION_MICRO

#define LIBFO_VERSION_MICRO 3

The micro component of the version of libfo available at compile-time.

LIBFO_VERSION_STRING

#define LIBFO_VERSION_STRING "0.6.3"

A string literal containing the version of libfo available at compile-time.

LIBFO_VERSION_EXTRA

#define LIBFO_VERSION_EXTRA ""

Extra compile-time version information string literal containing, e.g., the Subversion changeset number.

LIBFO_PIXELS_PER_INCH

#define LIBFO_PIXELS_PER_INCH 96

Pixels per inch for use with graphics without intrinsic size.

LIBFO_VERSION

#define             LIBFO_VERSION

The version of libfo available at compile-time, encoded using LIBFO_VERSION_ENCODE().

enum LibfoModuleEnum

The type of a module of libfo.

LibfoVersionInfo

typedef struct {
  LibfoModuleEnum module;
  const gchar    *nick;
  const gchar    *name;
  gint            compiled;
  const gchar    *compiled_string;
  gint            runtime;
  const gchar    *runtime_string;
} LibfoVersionInfo;

Collected version information about a component of libfo.

Other than nick , one or more of the parts of the LibfoVersionInfo may be 0 or NULL if the component is unable to report that information.
