[ Version ( since = "3.8" ) ]
public unowned string check_version (uint required_major, uint required_minor, uint required_micro)

Checks that the GOA library in use is compatible with the given version.

Generally you would pass in the constants MAJOR_VERSION, MINOR_VERSION, MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of GOA 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 and minor version).



the required major version.


the required minor version.


the required micro version.


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