curs_window(3X)						       curs_window(3X)

NAME
     curs_window:  newwin, delwin, mvwin, subwin, derwin, mvderwin, dupwin,
     wsyncup, syncok, wcursyncup, wsyncdown - create curses windows

SYNOPSIS
     #include <curses.h>

     WINDOW *newwin(int nlines, int ncols, int begin_y,
	  intbegin_x);

     int delwin(WINDOW *win);
     int mvwin(WINDOW *win, int y, int x);
     WINDOW *subwin(WINDOW *orig, int nlines, int ncols,
	  int begin_y, int begin_x);
     WINDOW *derwin(WINDOW *orig, int nlines, int ncols,
	  int begin_y, int begin_x);
     int mvderwin(WINDOW *win, int par_y, int par_x);
     WINDOW *dupwin(WINDOW *win);
     void wsyncup(WINDOW *win);
     int syncok(WINDOW *win, bool bf);
     void wcursyncup(WINDOW *win);
     void wsyncdown(WINDOW *win);

DESCRIPTION
     The newwin routine creates and returns a pointer to a new window with the
     given number of lines, nlines, and columns, ncols.	 The upper left-hand
     corner of the window is at line begin_y, column begin_x.  If either
     nlines or ncols is zero, they default to LINES - begin_y and COLS -
     begin_x.  A new full-screen window is created by calling newwin(0,0,0,0).

     The delwin routine deletes the named window, freeing all memory
     associated with it.  Subwindows must be deleted before the main window
     can be deleted.

     The mvwin routine moves the window so that the upper left-hand corner is
     at position (x, y).  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.

     The subwin routine creates and returns a pointer to a new window with the
     given number of lines, nlines, and columns, ncols.	 The window is at
     position (begin_y, begin_x) on the screen.	 (This position is relative to
     the screen, and not to the window orig.)  The window is made in the
     middle of the window orig, so that changes made to one window will affect
     both windows.  The subwindow shares memory with the window orig.  When
     using this routine, it is necessary to call touchwin or touchline on orig
     before calling wrefresh on the subwindow.

     The derwin routine is the same as subwin, except that begin_y and begin_x
     are relative to the origin of the window orig rather than the screen.
     There is no difference between the subwindows and the derived windows.

     The mvderwin routine 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.

     The dupwin routine creates an exact duplicate of the window win.

     Each curses window maintains two data structures: the character image
     structure and the status structure.  The character image structure is
     shared among all windows in the window hierarchy (i.e., the window with
     all subwindows).  The status structure, which contains information about
     individual line changes in the window, is private to each window.	The
     routine wrefresh uses the status data structure when performing screen
     updating.	Since status structures are not shared, changes made to one
     window in the hierarchy may not be properly reflected on the screen.

     The routine wsyncup causes the changes in the status structure of a
     window to be reflected in the status structures of its ancestors.	If
     syncok is called with second argument TRUE then wsyncup is called
     automatically whenever there is a change in the window.

     The routine wcursyncup updates the current cursor position of all the
     ancestors of the window to reflect the current cursor position of the
     window.

     The routine wsyncdown updates the status structure of the window to
     reflect the changes in the status structures of its ancestors.
     Applications seldom call this routine because it is called automatically
     by wrefresh.

RETURN VALUE
     Routines that return an integer return the integer ERR upon failure and
     an integer value other than ERR upon successful completion.

     delwin returns the integer ERR upon failure and OK upon successful
     completion.

     Routines that return pointers return NULL on error.

NOTES
     The header file <curses.h> automatically includes the header files
     <stdio.h> and <unctrl.h>.

     If many small changes are made to the window, the wsyncup option could
     degrade performance.
