PANGO_VERSION_ENCODE()

#define             PANGO_VERSION_ENCODE(major, minor, micro)

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

PANGO_VERSION

#define             PANGO_VERSION

The version of Pango available at compile-time, encoded using PANGO_VERSION_ENCODE().

PANGO_VERSION_MAJOR

#define PANGO_VERSION_MAJOR 1

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

PANGO_VERSION_MINOR

#define PANGO_VERSION_MINOR 22

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

PANGO_VERSION_MICRO

#define PANGO_VERSION_MICRO 2

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

PANGO_VERSION_STRING

#define PANGO_VERSION_STRING "1.22.2"

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

PANGO_VERSION_CHECK()

#define             PANGO_VERSION_CHECK(major,minor,micro)

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

pango_version ()

int                 pango_version                       (void);

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

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

Since 1.16

pango_version_string ()

const char*         pango_version_string                (void);

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

Since 1.16

pango_version_check ()

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

Checks that the Pango library in use is compatible with the given version. Generally you would pass in the constants PANGO_VERSION_MAJOR, PANGO_VERSION_MINOR, PANGO_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 Pango 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 PANGO_VERSION_CHECK().
