Type Definition MacTypes_sys::StrFileName

type StrFileName = Str63;

QuickTime 3.0:

The type StrFileName is used to make MacOS structs work cross-platform. For example FSSpec or SFReply previously contained a Str63 field. They now contain a StrFileName field which is the same when targeting the MacOS but is a 256 char buffer for Win32 and unix, allowing them to contain long file names.
