   const cchar_t *ts, const cchar_t *bs,


   const cchar_t *tl, const cchar_t *tr,


   const cchar_t *bl, const cchar_t *br);

int vline_set(


   const cchar_t *wch, int n);
int wvline_set(


   WINDOW *win,


   const cchar_t *wch, int n);
int mvvline_set(


   int y, int x,

   const cchar_t *wch, int n);

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:

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 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.

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 prefixed with “mv” first perform cursor movement and fail if the position (y, x) is outside the window boundaries.

NOTES¶

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

PORTABILITY¶

These functions are described in X/Open Curses, Issue 4.
