POSIX:2001 is the same as the "OpenGroup Base Specification Issue 6" and also known as "SUSv3". You find it on the web at http://www.opengroup.org/susv3/ > The open() would have to open or dup a file descriptor to the /dev/null > device to reserve a unique file descriptor, and then something needs to > map that file descriptor back to the pointer to the *DIR structure. Do you need a pointer to the DIR structure, or only memorize the filename of the directory? In the latter case, you can reuse most of the code from gnulib/lib/fchdir.c. Btw, does VMS have the dirfd function (as a function or as a macro)? It should return the file descriptor to a directory that is "held inside" a DIR structure. Bruno
