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 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.

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.
