NetBSD localhost 9.0 NetBSD 9.0 (GENERIC) #0: Fri Feb 14 00:06:28 UTC 2020 mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64
>Description:
hline() do not advance the cursor position. But with the following commands,i.e. when the line moves past the right-hand side of stdscr, the cursor moves to the next line.
>How-To-Repeat:
In tests/libcurses, the following test
include start
call OK mvhline 3 75 `\000A` 10
call OK refresh
gives [cup4;76XAAAAAcup5;76X] as the output. (COLS = 80 for testframe psuedo-terminal)
Equivalent C program,
#include <curses.h>
int main() {
initscr();
mvhline(3,COLS-5,'A', 10);
refresh();
getch();
endwin();
return 0;
}
