Function libnotcurses_sys::ncplane_rotate_cw

pub unsafe extern "C" fn ncplane_rotate_cw(n: *mut ncplane) -> c_int

Rotate the plane π/2 radians clockwise or counterclockwise. This cannot be performed on arbitrary planes, because glyphs cannot be arbitrarily rotated. The glyphs which can be rotated are limited: line-drawing characters, spaces, half blocks, and full blocks. The plane must have an even number of columns. Use the ncvisual rotation for a more flexible approach.
