Create and return a new window with the given number of lines (or rows),
nlines, and columns, ncols. The upper left corner of the
window is at line begy, column begx. If either nlines
or ncols is 0, they will be set to the value of
COLS-begx. A new full-screen
window is created by calling
Create and return a pointer to a new window with the given number of
lines (or rows), nlines, and columns, ncols. The window is
at position (begy, begx) 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. When using this routine, often it will
be necessary to call
touchline on orig
Deletes the window win, freeing up all memory associated with it. In the case of sub-windows, they should be deleted before the main window win.
These routines are called to write output to the terminal, as most other
routines merely manipulate data structures.
the window win to the physical terminal screen, taking into
account what is already there in order to minimize the amount of
information that’s sent to the terminal (called optimization). Unless
leaveok has been enabled, the physical cursor of the terminal is
left at the location of window win’s cursor. With
the number of characters output to the terminal is returned.
Move the window win so that the upper left corner will be at position (y, x). If the move would cause the window win to be off the screen, it is an error and the window win is not moved.
These routines overlay srcwin on top of dstwin; that is, all
text in srcwin is copied into dstwin. srcwin and
dstwin need not be the same size; only text where the two windows
overlap is copied. The difference is that

Throw away all optimization information about which parts of the window
win have been touched, by pretending that the entire window
win has been drawn on. This is sometimes necessary when using
overlapping windows, since a change to one window will affect the other
window, but the records of which lines have been changed in the other
window will not reflect the change.
touchline only pretends that
count lines have been changed, beginning with line start.
The cursor associated with the window win is moved to line (row) y,

which is (0, 0).
