FILE *tmpfile (void); The tmpfile() function generates a unique temporary filename using the path prefix P_tmpdir defined in <stdio.h>. The temporary file is then opened in binary read/write (w+b) mode. The file will be automatically deleted when it is closed or the program terminates. The tmpfile() function returns a stream descriptor, or NULL if a unique filename cannot be generated or the unique file cannot be opened. - EACCES
