/*
* filevms.c - scan directories and libaries on VMS
*
* 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().
*
* 02/09/95 (seiwald) - bungled R=[xxx] - was using directory length!
* 05/03/96 (seiwald) - split into pathvms.c
