cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \ -R /usr/xpg4/lib -lcurses [ library... ] c89 [ flag... ] file... -lcurses [ library... ] #include <curses.h> int mvderwin(WINDOW *win, int par_y, int par_x);
Is a pointer to the window to be mapped.
Is the y (row) coordinate of the placement of the upper left corner of window relative to the parent window.
Is the x (column) coordinate of the placement of the upper left corner of the window relative to the parent window.
The mvderwin() function defines a mapped area of win's parent window that is the same size as win and has its upper left corner at position par_y, par_x of the parent window.
Whenever win is refreshed, its contents are updated to match those of the mapped area and any reference to characters in win is treated as a reference to corresponding characters in the mapped area.
On success, the mvderwin() function returns OK. Otherwise, it returns ERR.
