+<H2>DESCRIPTION</H2><PRE>
+ The following routines give low-level access to various
+ <STRONG>curses</STRONG> capabilities. Theses routines typically are used
+ inside library routines.
+
+ The <STRONG>def_prog_mode</STRONG> and <STRONG>def_shell_mode</STRONG> routines save the
+ current terminal modes as the "program" (in <STRONG>curses</STRONG>) or
+ "shell" (not in <STRONG>curses</STRONG>) state for use by the
+ <STRONG>reset_prog_mode</STRONG> and <STRONG>reset_shell_mode</STRONG> routines. This is
+ done automatically by <STRONG>initscr</STRONG>. There is one such save
+ area for each screen context allocated by <STRONG>newterm()</STRONG>.
+
+ The <STRONG>reset_prog_mode</STRONG> and <STRONG>reset_shell_mode</STRONG> routines restore
+ the terminal to "program" (in <STRONG>curses</STRONG>) or "shell" (out of
+ <STRONG>curses</STRONG>) state. These are done automatically by <STRONG>endwin</STRONG>
+ and, after an <STRONG>endwin</STRONG>, by <STRONG>doupdate</STRONG>, so they normally are
+ not called.
+
+ The <STRONG>resetty</STRONG> and <STRONG>savetty</STRONG> routines save and restore the
+ state of the terminal modes. <STRONG>savetty</STRONG> saves the current
+ state in a buffer and <STRONG>resetty</STRONG> restores the state to what
+ it was at the last call to <STRONG>savetty</STRONG>.
+
+ The <STRONG>getsyx</STRONG> routine returns the current coordinates of the
+ virtual screen cursor in <EM>y</EM> and <EM>x</EM>. If <STRONG>leaveok</STRONG> is currently
+ <STRONG>TRUE</STRONG>, then <STRONG>-1</STRONG>,<STRONG>-1</STRONG> is returned. If lines have been removed
+ from the top of the screen, using <STRONG>ripoffline</STRONG>, <EM>y</EM> and <EM>x</EM>
+ include these lines; therefore, <EM>y</EM> and <EM>x</EM> should be used
+ only as arguments for <STRONG>setsyx</STRONG>.
+
+ The <STRONG>setsyx</STRONG> routine sets the virtual screen cursor to <EM>y</EM>, <EM>x</EM>.
+ If <EM>y</EM> and <EM>x</EM> are both <STRONG>-1</STRONG>, then <STRONG>leaveok</STRONG> is set. The two rou-
+ tines <STRONG>getsyx</STRONG> and <STRONG>setsyx</STRONG> are designed to be used by a
+ library routine, which manipulates <STRONG>curses</STRONG> windows but does
+ not want to change the current position of the program's
+ cursor. The library routine would call <STRONG>getsyx</STRONG> at the
+ beginning, do its manipulation of its own windows, do a
+ <STRONG>wnoutrefresh</STRONG> on its windows, call <STRONG>setsyx</STRONG>, and then call
+ <STRONG>doupdate</STRONG>.
+
+ The <STRONG>ripoffline</STRONG> routine provides access to the same facil-
+ ity that <STRONG>slk_init</STRONG> [see <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG>] uses to reduce the
+ size of the screen. <STRONG>ripoffline</STRONG> must be called before
+ <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> is called. If <EM>line</EM> is positive, a line
+ is removed from the top of <STRONG>stdscr</STRONG>; if <EM>line</EM> is negative, a
+ line is removed from the bottom. When this is done inside
+ <STRONG>initscr</STRONG>, the routine <STRONG>init</STRONG> (supplied by the user) is called
+ with two arguments: a window pointer to the one-line win-
+ dow that has been allocated and an integer with the number
+ of columns in the window. Inside this initialization rou-
+ tine, the integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> (defined in
+ <STRONG>&lt;curses.h&gt;</STRONG>) are not guaranteed to be accurate and <STRONG>wrefresh</STRONG>
+ or <STRONG>doupdate</STRONG> must not be called. It is allowable to call
+ <STRONG>wnoutrefresh</STRONG> during the initialization routine.
+
+ <STRONG>ripoffline</STRONG> can be called up to five times before calling
+ <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>.
+
+ The <STRONG>curs_set</STRONG> routine sets the cursor state is set to
+ invisible, normal, or very visible for <STRONG>visibility</STRONG> equal to
+ <STRONG>0</STRONG>, <STRONG>1</STRONG>, or <STRONG>2</STRONG> respectively. If the terminal supports the
+ <EM>visibility</EM> requested, the previous <EM>cursor</EM> state is
+ returned; otherwise, <STRONG>ERR</STRONG> is returned.
+
+ The <STRONG>napms</STRONG> routine is used to sleep for <EM>ms</EM> milliseconds.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ Except for <STRONG>curs_set</STRONG>, these routines always return <STRONG>OK</STRONG>.
+ <STRONG>curs_set</STRONG> returns the previous cursor state, or <STRONG>ERR</STRONG> if the
+ requested <EM>visibility</EM> is not supported.
+
+
+</PRE>
+<H2>NOTES</H2><PRE>
+ Note that <STRONG>getsyx</STRONG> is a macro, so <STRONG>&amp;</STRONG> is not necessary before
+ the variables <EM>y</EM> and <EM>x</EM>.
+
+ Older SVr4 man pages warn that the return value of
+ <STRONG>curs_set</STRONG> "is currently incorrect". This implementation
+ gets it right, but it may be unwise to count on the cor-
+ rectness of the return value anywhere else.
+
+ Both ncurses and SVr4 will call <STRONG>curs_set</STRONG> in <STRONG>endwin</STRONG> if
+ <STRONG>curs_set</STRONG> has been called to make the cursor other than
+ normal, i.e., either invisible or very visible. There is
+ no way for ncurses to determine the initial cursor state
+ to restore that.
+
+
+</PRE>
+<H2>PORTABILITY</H2><PRE>
+ The functions <STRONG>setsyx</STRONG> and <STRONG>getsyx</STRONG> are not described in the
+ XSI Curses standard, Issue 4. All other functions are as
+ described in XSI Curses.
+
+ The SVr4 documentation describes <STRONG>setsyx</STRONG> and <STRONG>getsyx</STRONG> as hav-
+ ing return type int. This is misleading, as they are
+ macros with no documented semantics for the return value.
