Declaration [src]

  guint required_major,
  guint required_minor,

)

Description [src]

Checks that the LunarDate library in use is compatible with the given version. Generally you would pass in the constants LUNAR_DATE_MAJOR_VERSION, LUNAR_DATE_MINOR_VERSION, LUNAR_DATE_MICRO_VERSION as the three arguments to this function; that produces a check that the library in use is compatible with the version of LunarDate 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.).

Available since: 2.4.0
