man 2 mkdir (create a directory - POSIX)
man 2 unlink (remove a file - POSIX)
man 3 remove (remove a file - POSIX/ANSI C)
man 2 rename (rename a file/move a file - POSIX/ANSI C)
I'm not sure about explicitly copying a file without writing a function
of your own...though that should be fairly easy, it's inconvienient and
won't take advantage of kernel side speed.
The GNU fileutils sources for cp.c (copy.c) just opens both files, and
uses a for loop. Based on that and a quick grep of /usr/src/linux/fs/*.c,
I can't find a system call to do it. Seems like it would be more efficient
if the data didn't have to cross between user/kernel space.
