A few special routines sometimes + need to be called before it; these are <STRONG>slk_init</STRONG>, <STRONG>filter</STRONG>, + <STRONG>ripoffline</STRONG>, <STRONG>use_env</STRONG>. For multiple-terminal applications, + <STRONG>newterm</STRONG> may be called before <STRONG>initscr</STRONG>. + + The initscr code determines the terminal type and initial- + izes all <STRONG>curses</STRONG> data structures. <STRONG>initscr</STRONG> also causes the + first call to <STRONG>refresh</STRONG> to clear the screen. If errors + occur, <STRONG>initscr</STRONG> writes an appropriate error message to + standard error and exits; otherwise, a pointer is returned + to <STRONG>stdscr</STRONG>. + + A program that outputs to more than one terminal should + use the <STRONG>newterm</STRONG> routine for each terminal instead of + <STRONG>initscr</STRONG>. A program that needs to inspect capabilities, so + it can continue to run in a line-oriented mode if the ter- + minal cannot support a screen-oriented program, would also + use <STRONG>newterm</STRONG>. The routine <STRONG>newterm</STRONG> should be called once + for each terminal. It returns a variable of type <STRONG>SCREEN</STRONG> <STRONG>*</STRONG> + which should be saved as a reference to that terminal. + The arguments are the <EM>type</EM> of the terminal to be used in + place of <STRONG>$TERM</STRONG>, a file pointer for output to the terminal, + and another file pointer for input from the terminal (if + <EM>type</EM> is <STRONG>NULL</STRONG>, <STRONG>$TERM</STRONG> will be used). The program must also + call <STRONG>endwin</STRONG> for each terminal being used before exiting + from <STRONG>curses</STRONG>. If <STRONG>newterm</STRONG> is called more than once for the + same terminal, the first terminal referred to must be the + last one for which <STRONG>endwin</STRONG> is called. + + A program should always call <STRONG>endwin</STRONG> before exiting or + escaping from <STRONG>curses</STRONG> mode temporarily. This routine + restores tty modes, moves the cursor to the lower left- + hand corner of the screen and resets the terminal into the + proper non-visual mode. Calling <STRONG>refresh</STRONG> or <STRONG>doupdate</STRONG> after + a temporary escape causes the program to resume visual + mode. + + The <STRONG>isendwin</STRONG> routine returns <STRONG>TRUE</STRONG> if <STRONG>endwin</STRONG> has been + called without any subsequent calls to <STRONG>wrefresh</STRONG>, and <STRONG>FALSE</STRONG> + otherwise. + + The <STRONG>set_term</STRONG> routine is used to switch between different + terminals. The screen reference <STRONG>new</STRONG> becomes the new cur- + rent terminal. The previous terminal is returned by the + routine. This is the only routine which manipulates + <STRONG>SCREEN</STRONG> pointers; all other routines affect only the cur- + rent terminal. + + The <STRONG>delscreen</STRONG> routine frees storage associated with the + <STRONG>SCREEN</STRONG> data structure. The <STRONG>endwin</STRONG> routine does not do + this, so <STRONG>delscreen</STRONG> should be called after <STRONG>endwin</STRONG> if a par- + ticular <STRONG>SCREEN</STRONG> is no longer needed. + + +</PRE> +<H2>RETURN VALUE</H2><PRE> + <STRONG>endwin</STRONG> returns the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> upon + successful completion. + + Routines that return pointers always return <STRONG>NULL</STRONG> on error. + + +</PRE> +<H2>NOTES</H2><PRE> + Note that <STRONG>initscr</STRONG> and <STRONG>newterm</STRONG> may be macros. + + +</PRE> +<H2>PORTABILITY</H2><PRE> + These functions are described in the XSI Curses standard, + Issue 4. It specifies that portable applications must not + call <STRONG>initscr</STRONG> more than once. + + Old versions of curses, e.g., BSD 4.4, may have returned a + null pointer from <STRONG>initscr</STRONG> when an error is detected, + rather than exiting. It is safe but redundant to check + the return value of <STRONG>initscr</STRONG> in XSI Curses. + + +</PRE> +<H2>SEE ALSO</H2><PRE> + <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, <STRONG><A HREF="curs_kernel.3x.html">curs_kernel(3x)</A></STRONG>, <STRONG><A HREF="curs_refresh.3x.html">curs_refresh(3x)</A></STRONG>, + <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG>, <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG> + + + + + + + + + + + + + + + + + +</PRE> +<HR> +<ADDRESS> +Man(1) output converted with +<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a> +</ADDRESS> +</BODY> +</HTML> |
