FILE *tmpfile(void)

char *tmpnam(char *s)

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 FILE* opened in update mode (see fopen (2)).

Tmpnam generates a string that is a valid file name and that is not the same as the name of an existing file. If s is zero, it returns a pointer to a string which may be overwritten by subsequent calls to tmpnam . If s is non-zero, it should point to an array of at least L_tmpnam (defined in <stdio.h> ) characters, and the answer will be copied there.
