.. function:: wrapper(func, ...)
Initialize curses and call another callable object, *func*, which should be the
rest of your curses-using application. If the application raises an exception,
this function will restore the terminal to a sane state before re-raising the
exception and generating a traceback. The callable object *func* is then passed
the main window 'stdscr' as its first argument, followed by any other arguments
passed to :func:`wrapper`. Before calling *func*, :func:`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.

:mod:`curses.wrapper` --- Terminal handler for curses programs
==============================================================
.. module:: curses.wrapper
:synopsis: Terminal configuration wrapper for curses programs.
.. moduleauthor:: Eric Raymond <esr@thyrsus.com>
.. sectionauthor:: Eric Raymond <esr@thyrsus.com>
This module supplies one function, :func:`wrapper`, which runs another function
which should be the rest of your curses-using application. If the application
raises an exception, :func:`wrapper` will restore the terminal to a sane state
before re-raising the exception and generating a traceback.
.. function:: 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 :func:`wrapper`.
Before calling the hook function, :func:`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.
