6.14 curses.wrapper --
Terminal handler for curses programs



New in version 1.6.


This module supplies one function, wrapper(), which runs
another function which should be the rest of your curses-using
application. If the application raises an exception,
wrapper() will restore the terminal to a sane state before
passing it further up the stack and generating a traceback.


wrapper (func, ...)

Wrapper function that initializes curses and calls another function,
func, restoring normal keyboard/screen behavior on error.
The callable object func is then passed the main window 'stdscr'
as its first argument, followed by any other arguments passed to
wrapper().



Before calling the hook function, wrapper() turns on cbreak
mode, turns off echo, enables the terminal keypad, and initializes
colors if the terminal has color support. On exit (whether normally
or by exception) it restores cooked mode, turns on echo, and disables
the terminal keypad.
