| 66 | This module supplies one function, <tt class="function">wrapper()</tt>, which runs |
| 67 | another function which should be the rest of your curses-using |
| 68 | application. If the application raises an exception, |
| 69 | <tt class="function">wrapper()</tt> will restore the terminal to a sane state before |
| 70 | re-raising the exception and generating a traceback. |

| 76 | <dd> |
| 77 | Wrapper function that initializes curses and calls another function, |
| 78 | <var>func</var>, restoring normal keyboard/screen behavior on error. |
| 79 | The callable object <var>func</var> is then passed the main window 'stdscr' |
| 80 | as its first argument, followed by any other arguments passed to |
| 81 | <tt class="function">wrapper()</tt>. |
| 82 | </dl> |
| 83 | |
| 84 | <P> |
| 85 | Before calling the hook function, <tt class="function">wrapper()</tt> turns on cbreak |
| 86 | mode, turns off echo, enables the terminal keypad, and initializes |
| 87 | colors if the terminal has color support. On exit (whether normally |
| 88 | or by exception) it restores cooked mode, turns on echo, and disables |
| 89 | the terminal keypad. |
