One thing came to mind.  Instead of readdir() and friends, if I could
specify the O_EXCL option to fopen(), I'd know if the file already
exists, then would change the filename and try again.  Trouble is,
unlike open(), fopen() doesn't take an O_EXCL option.  glibc fopen()
supports an "x" mode string which adds O_EXCL to the underlying open()
call, but that's not portable.  How about using open() directly?  open()
yields a file descriptor, not a stream (a.k.a. FILE) pointer, so either
use fdopen() to convert (again, nonportable) or switch from fwrite() to
write() (is that portable enough?).
