The following routines give low-level access to various
- <STRONG>curses</STRONG> capabilities. Theses routines typically are used
+ <STRONG>curses</STRONG> capabilities. These routines typically are used
inside library routines.
+
+</PRE>
+<H3><a name="h3-def_prog_mode_-def_shell_mode">def_prog_mode, def_shell_mode</a></H3><PRE>
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>re-</STRONG>
automatically by <STRONG>initscr</STRONG>. There is one such save area for
each screen context allocated by <STRONG>newterm()</STRONG>.
+
+</PRE>
+<H3><a name="h3-reset_prog_mode_-reset_shell_mode">reset_prog_mode, reset_shell_mode</a></H3><PRE>
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.
+
+</PRE>
+<H3><a name="h3-resetty_-savetty">resetty, savetty</a></H3><PRE>
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>.
+
+</PRE>
+<H3><a name="h3-getsyx">getsyx</a></H3><PRE>
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
clude these lines; therefore, <EM>y</EM> and <EM>x</EM> should be used only
as arguments for <STRONG>setsyx</STRONG>.
+
+</PRE>
+<H3><a name="h3-setsyx">setsyx</a></H3><PRE>
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 li-
<STRONG>wnoutrefresh</STRONG> on its windows, call <STRONG>setsyx</STRONG>, and then call
<STRONG>doupdate</STRONG>.
+
+</PRE>
+<H3><a name="h3-ripoffline">ripoffline</a></H3><PRE>
The <STRONG>ripoffline</STRONG> routine provides access to the same facili-
ty 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><curses.h></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>initscr</STRONG> or <STRONG>newterm</STRONG> is called, to prepare these initial ac-
+ tions:
+
+ <STRONG>o</STRONG> If <EM>line</EM> is positive, a line is removed from the top of
+ <STRONG>stdscr</STRONG>.
+
+ <STRONG>o</STRONG> if <EM>line</EM> is negative, a line is removed from the bot-
+ tom.
+
+ When the resulting initialization is done inside <STRONG>initscr</STRONG>,
+ the routine <STRONG>init</STRONG> (supplied by the user) is called with two
+ arguments:
+
+ <STRONG>o</STRONG> a window pointer to the one-line window that has been
+ allocated and
+
+ <STRONG>o</STRONG> an integer with the number of columns in the window.
+
+ Inside this initialization routine, the integer variables
+ <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> (defined in <STRONG><curses.h></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 in-
- visible, 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 re-
- turned; otherwise, <STRONG>ERR</STRONG> is returned.

The <STRONG>napms</STRONG> routine is used to sleep for <EM>ms</EM> milliseconds.

-<H2>RETURN VALUE</H2><PRE>
+<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></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
X/Open defines no error conditions. In this implementa-
tion
- <STRONG>def_prog_mode</STRONG>, <STRONG>def_shell_mode</STRONG>, <STRONG>reset_prog_mode</STRONG>, <STRONG>re-</STRONG>
- <STRONG>set_shell_mode</STRONG>
- return an error if the terminal was not ini-
- tialized, or if the I/O call to obtain the
- terminal settings fails.

+ fails.
- <STRONG>ripoffline</STRONG>
- returns an error if the maximum number of
- ripped-off lines exceeds the maximum (NRIPS =
- 5).

-<H2>NOTES</H2><PRE>
+<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
Note that <STRONG>getsyx</STRONG> is a macro, so <STRONG>&</STRONG> is not necessary before
the variables <EM>y</EM> and <EM>x</EM>.
</PRE>
-<H2>PORTABILITY</H2><PRE>
+<H2><a name="h2-PORTABILITY">PORTABILITY</a></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.
