Function libnotcurses_sys::ncplane_at_yx_cell

pub unsafe extern "C" fn ncplane_at_yx_cell(
    n: *mut ncplane, 
    y: c_int, 
    x: c_int, 
    c: *mut nccell
) -> c_int

Retrieve the current contents of the specified cell into ‘c’. This cell is invalidated if the associated plane is destroyed. Returns the number of bytes in the EGC, or -1 on error. Unlike ncplane_at_yx(), when called upon the secondary columns of a wide glyph, the return can be distinguished from the primary column (nccell_wide_right_p(c) will return true).
