* Description:
|
|
* border(), wborder(), and box() draw a border around the edge of
|
|
* the window. If any argument is zero, an appropriate default is
|
|
* used:
|
|
*
|
|
* ls left side of border ACS_VLINE
|
|
* rs right side of border ACS_VLINE
|
|
* ts top side of border ACS_HLINE
|
|
* bs bottom side of border ACS_HLINE
|
|
* tl top left corner of border ACS_ULCORNER
|
|
* tr top right corner of border ACS_URCORNER
|
|
* bl bottom left corner of border ACS_LLCORNER
|
|
* br bottom right corner of border ACS_LRCORNER
|
|
*
|
|
* hline() and whline() draw a horizontal line, using ch, starting
|
|
* from the current cursor position. The cursor position does not
|
|
* change. The line is at most n characters long, or as many as
|
|
* will fit in the window.
|
|
*
|
|
* vline() and wvline() draw a vertical line, using ch, starting
|
|
* from the current cursor position. The cursor position does not
|
|
* change. The line is at most n characters long, or as many as
|
|
* will fit in the window.
|
|
*
|
|
* Return Value:
|
|
* These functions return OK on success and ERR on error.
