|#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().

If you entered a >20 character filename, I wouldn't be that surprised
if something went wrong ...
