check_version

Description:

[ 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 [const@Goa.MAJOR_VERSION], [const@Goa.MINOR_VERSION], [const@Goa.MICRO_VERSION] as 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).

Parameters:

required_major	the required major version.
required_minor	the required minor version.
required_micro	the required micro version.

Returns:

null if the GOA library is compatible with the given version, or a string describing the version mismatch.
