is_absolute_file_name(+File)

True if File specifies an absolute path name. On POSIX systems, this implies the path starts with a‘/’. For Microsoft-based systems this implies the path starts with <letter>: or //<host>/. This predicate is intended to provide platform-independent checking for absolute paths. See also absolute_file_name/2 and prolog_to_os_filename/2.
