version_check


Description:


[ Version ( since = "1.16" ) ]
public unowned string? 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 VERSION_MAJOR, VERSION_MINOR, 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. gint.required_minor.required_micro. Second the running library must be binary compatible with the version required_major.gint.required_minor.required_micro (same major version.)

For compile-time version checking use PANGO_VERSION_CHECK.

Parameters:

required_major

the required major version.

required_minor

the required minor version.

required_micro

the required major version.

Returns:

null if the Pango library is compatible with the given version, or a string describing the version mismatch. The returned string is owned by Pango and should not be modified or freed.
