temp files under C

[Brian May <bam@debian.org>]

Hello,

what is the safest way to open/create a temporary file under C, and
get a string with the filename?

So far, I have seen:

tmpfile        looks ok, but how do I get the filename?
tmpnam         not secure
tmpnam_r       not secure
tempnam        not secure
mktemp         not secure
mkstemp        returns a file handle, but I want a FILE*.

so, at the moment mkstemp combined with fdopen looks the most hopeful.
Is this the best way?

However, that man page says:

       Don't use this function, use tmpfile(3) instead. It's bet­
       ter defined and more portable.

:-(

...also I assume (hope!) that mkstemp doesn't delete the file when it
is closed. Is this correct?
