If you are at all interested in portability, the functions you
need are called opendir, readdir, and closedir, which neither
Microsoft nor (apparently) Borland have seen fit to provide.
These routines are in the POSIX standard and are the universally
recommended way of reading directories from within a C program.
Several implementations of MS-DOS opendir/readdir exist: I have
written one or two, which I can supply upon request; I have given
mine to Doug Gwyn for inclusion in his posted opendir/readdir
package; I have also heard that the FSF has an implementation so
that their tools can be ported to MS-DOS (if you have enough
memory :-) ).
