/*
 * filemac.c - manipulate file names and scan directories on macintosh
 *
 * External routines:
 *
 *	file_dirscan() - scan a directory for files
 *	file_time() - get timestamp of file, if not done by file_dirscan()
 *	file_archscan() - scan an archive for files
 *
 * File_dirscan() and file_archscan() call back a caller provided function
 * for each file found.  A flag to this callback function lets file_dirscan()
 * and file_archscan() indicate that a timestamp is being provided with the
 * file.   If file_dirscan() or file_archscan() do not provide the file's
 * timestamp, interested parties may later call file_time().
 *
 * 04/08/94 (seiwald) - Coherent/386 support added.
 * 12/19/94 (mikem) - solaris string table insanity support
 * 02/14/95 (seiwald) - parse and build /xxx properly
 * 05/03/96 (seiwald) - split into pathunix.c
 * 11/21/96 (peterk) - BEOS does not have Unix-style archives
 * 01/21/00 (malyn) - divorced from GUSI
 * 01/08/01 (seiwald) - closure param for file_dirscan/file_archscan
 * 11/04/02 (seiwald) - const-ing for string literals
