Usage of wscanw() from curses library

Under Ultrix 4.0 on a DS5000 I am having trouble with the function
wscanw() in the curses library.

Here is test program that I wrote to demonstrate the problem.

#include <stdio.h>
#include <curses.h>
#include <signal.h>

main()
{
    char filename[20];

    initscr();
    wmove(stdscr, 18, 1);
    wrefresh(stdscr);

    wscanw(stdscr, "%s", filename);
    endwin();

    printf("filename: %s\n", filename);
}

This was compiled with the command:

    cc -g -o scan scan.c -lcurses -ltermlib

When the program is run, the cursor is positioned correctly and it
waits for input.  After entering some text and pressing return, I
expected the program to end.  It does not.  It seems to hang up and I
have to kill the process from another window.  Interrupts are ignored
as well.

I ran the program in the debugger and it never returns from wscanw().

Hope someone can provide some help.  Thanks.
