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+").
