These functions draw lines on stdscr or on the specified window.
The hline() function draws a horizontal line of the character ch on
stdscr starting at the current cursor position and extending for n char-
acters, or until the right hand side of stdscr is reached. If the text
portion of ch is 0 then the line will be drawn with the ACS_HLINE charac-
The whline() function is the same as the hline() function, excepting that
the line is drawn in the window specified by win.
The vline() function draws a vertical line of character ch on stdscr
starting at the current cursor position and moving down until either n
characters have been drawn or the bottom of stdscr is reached. If the
text portion of ch is 0 then the line will be drawn with the ACS_VLINE
The wvline() function is the same as the vline() function, excepting that
the line is drawn on the given window.
The mvhline(), mvwhline(), mvvline() and mvwvline() functions are the
same as the hline(), whline(), vline() and wvline() functions, respec-
tively, excepting that wmove() is called to move the cursor to the posi-
tion specified by y, x before the line is drawn on the window.
Functions returning pointers will return NULL if an error is detected.
The functions that return an int will return one of the following values:
OK The function completed successfully.
ERR An error occurred in the function.
The NetBSD Curses library complies with the X/Open Curses specification,
part of the Single Unix Specification.
The use of ACS_HLINE and ACS_VLINE as default drawing character in
hline() and vline() is a NetBSD extension which should not be relied on
in portable code.
The Curses package appeared in 4.0BSD.
