/*
|
|
|
|
* An example of the 'filter()' function in ncurses, this program prompts
|
|
|
|
* for commands and executes them (like a command shell). It illustrates
|
|
|
|
* how ncurses can be used to implement programs that are not full-screen.
|
|
|
|
*
|
|
|
|
* Ncurses differs slightly from SVr4 curses. The latter does not flush its
|
|
|
|
* state when exiting program mode, so the attributes on the command lines of
|
|
|
|
* this program 'bleed' onto the executed commands. Rather than use the
|
|
|
|
* reset_shell_mode() and reset_prog_mode() functions, we could invoke endwin()
|
|
|
|
* and refresh(), but that does not work any better.
