How to clear a specific line with NCurses?

maybe crltoeol would do the trick

This is how I ended up doing it for my purposes.

int y, x;            // to store where you are
getyx(stdscr, y, x); // save current pos
move(y, 0);          // move to begining of line
clrtoeol();          // clear line
move(y, x);          // move back to where you were

You can position on the line you want to clear and then call clrtoeol function.
