You may want to use the 'FILE * tmpfile(void)' function from stdlib.

from the man:

DESCRIPTION

The tmpfile() function shall create a temporary file and open a corresponding stream. The file shall be automatically deleted when all references to the file are closed. The file is opened as in fopen() for update (w+).

In some implementations, a permanent file may be left behind if the process calling tmpfile() is killed while it is processing a call to tmpfile().

An error message may be written to standard error if the stream cannot be opened.
