NAME
     tmpfile - create a temporary file

SYNOPSIS
     #include <stdio.h>

     FILE *tmpfile ()

DESCRIPTION
     tmpfile creates a temporary file using a name generated by tmpnam(3S),
     and returns a corresponding FILE pointer.  If the file cannot be opened,
     an error message is printed using perror(3C), and a NULL pointer is
     returned.  The file will automatically be deleted when the process using
     it terminates.  The file is opened for update ("w+").
