DESCRIPTION

The tmpfile() function creates a temporary file using a name generated by tmpnam(3STDC), and returns a corresponding FILE pointer. If the file cannot be opened, an error message is printed using perror(3STDC), 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+").

RESTRICTIONS

If a thread is deleted while performing tmpfile, it is possible that the temporary file will not be deleted when the program terminates.
