Check the functions tempnam() and tmpnam, these allow you to create
unique filenames.  Then just use those to open a file for temporary
access.  Also, there is a function tmpfile() which will return a
unique file descriptor.  (I think that this function is only availible
with ANSI C, though?)  Hope this helps some!

if you're using SunOS 4.x.x,  your best bet is to use mktemp(),
but FILE *tmpfile() and char *tmpnam() are ANSI, and _should_ work
on everything.

from TFM (SunOS 4.1.3)

mkstemp()  makes
the  same  replacement  to  the  template but returns a file
descriptor for the template file open for reading and  writ-
ing.   mkstemp() avoids the race between testing whether the
file exists and opening it for use.

So mkstemp() is the safest bet to avoid any race conditions ...
