3 NAME
4 tiny curses - screen functions without ``optimal'' cursor
5 motion

7 SYNOPSIS
8 cc [flags] files tc.o -ltermlib [libraries]

10 DESCRIPTION
11 These routines give the programmer the high level curses(3)
12 interface to the termcap(3) functions without the overhead
13 of the curses(3) screen optimization capabilities. Tiny
14 curses is useful for simple screen formatting and is more
15 efficient for displays that do not require significant
16 redrawing.
17
18 To use the routines, the function initscr() should be called
19 before any others. The routine endwin() should be called
20 before exiting.
21
22 The names of the functions are identical to those of
23 curses(3) so that it is easy to move from Tiny curses to
24 real curses(3). There are many functions provided by
25 curses(3) that are not provided here (e.g., windows), so the
26 opposite translation is more difficult.

80 NOTES
81 The refresh() function is actually a call to fflush(stdout)
82 to flush the output buffer. Thus, the tiny curses refresh()
83 may be used to guarantee that some text is on the screen,
84 but it might go out sooner.
85
86 Tiny curses assumes you want to catch interrupts, so
87 initscr() sets things up so that an interrupt will reset the
88 tty, move to the bottom of the screen, and exit.
