|
|
* fileos2.c - scan directories and archives on NT
|
|
*
|
|
* 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().
|
|
*
|
|
* 07/10/95 (taylor) Findfirst() returns the first file on NT.
|
|
* 05/03/96 (seiwald) split apart into pathnt.c
|
|
* 01/20/00 (seiwald) - Upgraded from K&R to ANSI C
|
|
* 09/22/00 (seiwald) handle \ and c:\ specially: don't add extra /
|
|
* 01/08/01 (seiwald) - closure param for file_dirscan/file_archscan
|
|
* 11/04/02 (seiwald) - const-ing for string literals
