The border_set and wborder_set functions draw a border around the
edges of the current or specified window. These functions do not
change the cursor position, and do not wrap.
Other than the window, each argument is a complex character with
ls - left side,
rs - right side,
ts - top side,
bs - bottom side,
tl - top left-hand corner,
tr - top right-hand corner,
bl - bottom left-hand corner, and
br - bottom right-hand corner.
If any of these arguments is zero, then the corresponding default
values (defined in curses.h) are used instead:
box_set(win, verch, horch); is a shorthand for the following
wborder_set(win, verch, verch,horch, horch, NULL, NULL, NULL, NULL);
The *line_set functions use wch to draw a line starting at the
current cursor position in the window. The line is at most n
characters long or as many as fit into the window. The current
cursor position is not changed.
The hline_set, mvhline_set, mvwhline_set, and whline_set
functions draw a line proceeding toward the last column of the
The vline_set, mvvline_set, mvwvline_set, and wvline_set
functions draw a line proceeding toward the last line of the
Upon successful completion, these functions return OK.
Otherwise, they return ERR.
Functions using a window parameter return an error if it 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.
