FILE    *tmpfile(void)

SH DESCRIPTION
I Tmpfile
creates a temporary file that will automatically
be removed when the file is closed or the program exits.
The return value is a Stdio
B FILE*
opened in update mode (see
IR fopen (2)).
PP
I Tmpnam
generates a string that is a valid file name and that is not
the same as the name of an existing file.
If
I s
is zero, it returns a pointer to a string which may be overwritten by
subsequent calls to
IR tmpnam .
If
I s
is non-zero, it should point to an array of at least
B L_tmpnam
(defined in
BR <stdio.h> )
characters, and the answer will be copied there.

or if the program terminates abnormally.
