hb-version — Information about the version of HarfBuzz in use

Functions

#define	HB_VERSION_ATLEAST()
void	hb_version ()
hb_bool_t	hb_version_atleast ()
const char *	hb_version_string ()

Types and Values

#define	HB_VERSION_MAJOR
#define	HB_VERSION_MICRO
#define	HB_VERSION_MINOR
#define	HB_VERSION_STRING

Includes

#include <hb.h>

Description

These functions and macros allow accessing version of the HarfBuzz library used at compile- as well as run-time, and to direct code conditionally based on those versions, again, at compile- or run-time.

Functions

HB_VERSION_ATLEAST()

#define             HB_VERSION_ATLEAST(major,minor,micro)

Tests the library version at compile-time against a minimum value, as three integer components.

Parameters

major	the major component of the version number
minor	the minor component of the version number
micro	the micro component of the version number

hb_version ()

void
hb_version (unsigned int *major,
            unsigned int *minor,
            unsigned int *micro);

Returns library version as three integer components.

Parameters

major	Library major version component.	[out]
minor	Library minor version component.	[out]
micro	Library micro version component.	[out]

Since: 0.9.2

hb_version_atleast ()

hb_bool_t
hb_version_atleast (unsigned int major,
                    unsigned int minor,
                    unsigned int micro);

Tests the library version against a minimum value, as three integer components.

Parameters

major	Library major version component
minor	Library minor version component
micro	Library micro version component

Returns

true if the library is equal to or greater than the test value, false otherwise

Since: 0.9.30

hb_version_string ()

const char *
hb_version_string (void);

Returns library version as a string with three components.

Returns

Library version string

Since: 0.9.2

Types and Values

HB_VERSION_MAJOR

#define             HB_VERSION_MAJOR

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

HB_VERSION_MICRO

#define             HB_VERSION_MICRO

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

HB_VERSION_MINOR

#define             HB_VERSION_MINOR

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

HB_VERSION_STRING

#define             HB_VERSION_STRING

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