Normally, the hardware cursor is left at the location of
the window cursor being refreshed. The <STRONG>leaveok</STRONG> option al-
lows the cursor to be left wherever the update happens to

window. The <EM>top</EM> and <EM>bot</EM> parameters are the line numbers

The <STRONG>scrollok</STRONG> option controls what happens when the cursor
of a window is moved off the edge of the window or

call <STRONG>idlok</STRONG>).

input, and whether it translates newline into return and
the return key.

an integer always return <STRONG>OK</STRONG>.

These functions are described in the XSI Curses standard,
Issue 4.

+ trolled by <STRONG>nl</STRONG> and <STRONG>nonl</STRONG>. BSD curses did turn off these
translations; AT&T curses (at least as late as SVr1) did
not. We choose to do so, on the theory that a programmer
requesting raw input wants a clean (ideally 8-bit clean)
