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. |
