Yes there is, but (obviously, being a system call) it's not
portable.

The POSIX way to do it is to use operdir(), dirent(), rewinddir()
and closedir(). These should all be in section 2 of your man
pages... chdir() and fchdir() can be used to change directories,
and then normal file i/o operations can be used once you have the
file(s) you want.
