If any of these arguments is zero, then the corresponding default values (defined in curses.h) are used instead:
box(win, verch, horch) is a shorthand for the following call: wborder(win, verch, verch, horch, horch, 0, 0, 0, 0).
The hline and whline functions draw a horizontal (left to right) line using ch starting at the current cursor position in the window. The current cursor position is not changed. The line is at most n characters long, or as many as fit into the window.
The vline and wvline functions draw a vertical (top to bottom) line using ch starting at the current cursor position in the window. The current cursor position is not changed. The line is at most n characters long, or as many as fit into the window.
X/Open does not define any error conditions. This implementation returns an error if the window pointer is null.
Functions with a ``mv'' prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null.
Note that border and box may be macros.
