Function libnotcurses_sys::ncplane_erase_region

pub unsafe extern "C" fn ncplane_erase_region(
    n: *mut ncplane, 
    ystart: c_int, 
    xstart: c_int, 
    ylen: c_int, 
    xlen: c_int
) -> c_int

Erase every cell in the region starting at {ystart, xstart} and having size {ylen, xlen}. It is an error if any of ystart, xstart, ylen, or xlen is negative. A value of 0 may be provided for ylen and/or xlen, meaning to erase everything along that dimension. It is an error if ystart + ylen or xstart + xlen is not in the plane.
