-<H2>DESCRIPTION</H2><PRE>
- Calling <STRONG>newwin</STRONG> creates and returns a pointer to a new win-
- dow with the given number of lines and columns. 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 memo-
- ry associated with it (it does not actually erase the win-
- dow'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) in-
- side its parent window. The screen-relative parameters of
- the window are not changed. This routine is used to dis-
- play 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 whenev-
- er 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.

+
+ The functions which return a window pointer may also fail if there is
+ insufficient memory for its data structures. Any of these functions
+ will fail if the screen has not been initialized, i.e., with <STRONG>initscr</STRONG> or
