The upper + left-hand corner of the window is at line <EM>begin</EM>_<EM>y</EM>, column + <EM>begin</EM>_<EM>x</EM>. If either <EM>nlines</EM> or <EM>ncols</EM> is zero, they default + to <STRONG>LINES</STRONG> <STRONG>-</STRONG> <EM>begin</EM>_<EM>y</EM> and <STRONG>COLS</STRONG> <STRONG>-</STRONG> <EM>begin</EM>_<EM>x</EM>. A new full-screen + window is created by calling <STRONG>newwin(0,0,0,0)</STRONG>. + + Calling <STRONG>delwin</STRONG> deletes the named window, freeing all mem- + ory associated with it (it does not actually erase the + window's screen image). Subwindows must be deleted before + the main window can be deleted. + + Calling <STRONG>mvwin</STRONG> moves the window so that the upper left-hand + corner is at position (<EM>x</EM>, <EM>y</EM>). If the move would cause the + window to be off the screen, it is an error and the window + is not moved. Moving subwindows is allowed, but should be + avoided. + + Calling <STRONG>subwin</STRONG> creates and returns a pointer to a new win- + dow with the given number of lines, <EM>nlines</EM>, and columns, + <EM>ncols</EM>. The window is at position (<EM>begin</EM>_<EM>y</EM>, <EM>begin</EM>_<EM>x</EM>) on + the screen. (This position is relative to the screen, and + not to the window <EM>orig</EM>.) The window is made in the middle + of the window <EM>orig</EM>, so that changes made to one window + will affect both windows. The subwindow shares memory + with the window <EM>orig</EM>. When using this routine, it is nec- + essary to call <STRONG>touchwin</STRONG> or <STRONG>touchline</STRONG> on <EM>orig</EM> before call- + ing <STRONG>wrefresh</STRONG> on the subwindow. + + Calling <STRONG>derwin</STRONG> is the same as calling <STRONG>subwin,</STRONG> except that + <EM>begin</EM>_<EM>y</EM> and <EM>begin</EM>_<EM>x</EM> are relative to the origin of the win- + dow <EM>orig</EM> rather than the screen. There is no difference + between the subwindows and the derived windows. + + Calling <STRONG>mvderwin</STRONG> moves a derived window (or subwindow) + inside its parent window. The screen-relative parameters + of the window are not changed. This routine is used to + display different parts of the parent window at the same + physical position on the screen. + + Calling <STRONG>dupwin</STRONG> creates an exact duplicate of the window + <EM>win</EM>. + + Calling <STRONG>wsyncup</STRONG> touches all locations in ancestors of <EM>win</EM> + that are changed in <EM>win</EM>. If <STRONG>syncok</STRONG> is called with second + argument <STRONG>TRUE</STRONG> then <STRONG>wsyncup</STRONG> is called automatically when- + ever there is a change in the window. + + The <STRONG>wsyncdown</STRONG> routine touches each location in <EM>win</EM> that + has been touched in any of its ancestor windows. This + routine is called by <STRONG>wrefresh</STRONG>, so it should almost never + be necessary to call it manually. + + The routine <STRONG>wcursyncup</STRONG> updates the current cursor position + of all the ancestors of the window to reflect the current + cursor position of the window. + + +</PRE> +<H2>RETURN VALUE</H2><PRE> + Routines that return an integer return the integer <STRONG>ERR</STRONG> + upon failure and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value + other than <STRONG>ERR</STRONG>") upon successful completion. + + <STRONG>delwin</STRONG> returns the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> upon + successful completion. + + Routines that return pointers return <STRONG>NULL</STRONG> on error. + + +</PRE> +<H2>NOTES</H2><PRE> + If many small changes are made to the window, the <STRONG>wsyncup</STRONG> + option could degrade performance. + + Note that <STRONG>syncok</STRONG> may be a macro. + + +</PRE> +<H2>BUGS</H2><PRE> + The subwindow functions (<EM>subwin</EM>, <EM>derwin</EM>, <EM>mvderwin</EM>, <STRONG>wsyn-</STRONG> + <STRONG>cup</STRONG>, <STRONG>wsyncdown</STRONG>, <STRONG>wcursyncup</STRONG>, <STRONG>syncok</STRONG>) are flaky, incom- + pletely implemented, and not well tested. + + The System V curses documentation is very unclear about + what <STRONG>wsyncup</STRONG> and <STRONG>wsyncdown</STRONG> actually do. It seems to imply + that they are only supposed to touch exactly those lines + that are affected by ancestor changes. The language here, + and the behavior of the <STRONG>curses</STRONG> implementation, is pat- + terned on the XPG4 curses standard.
