NAME
       tmpfile - create a temporary file

SYNOPSIS
       #include <stdio.h>
       FILE *tmpfile (void);

DESCRIPTION
       tmpfile creates a temporary file using a name generated by the tmpnam
       routine and returns a corresponding FILE pointer.  If the file cannot
       be opened, a NULL pointer is returned.  The file is automatically
       deleted when the process using it terminates or when the file is
       closed.  The file is opened for update ("w+").
