DESCRIPTION

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 attributes:

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:

WACS_VLINE,

WACS_VLINE,

WACS_HLINE,

WACS_HLINE,

WACS_ULCORNER,

WACS_URCORNER,

WACS_LLCORNER, and

WACS_LRCORNER.

box_set(win, verch, horch); is a shorthand for the following call:

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 same line.

The vline_set, mvvline_set, mvwvline_set, and wvline_set functions draw a line proceeding toward the last line of the window.

NOTES

Note that border_set, hline_set, mvhline_set, mvvline_set, mvwhline_set, mvwvline_set, and vline_set may be macros.

RETURN VALUE

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.
