Function ncplane_putnstr 

pub fn ncplane_putnstr(
    plane: &mut NcPlane,
    num_bytes: usize,
    string: &str,
) -> NcResult_i32

Writes a string to the current location, using the current style, and no more than num_bytes bytes will be written.

Advances the cursor by some positive number of columns (though not beyond the end of the plane); this number is returned on success.

On error, a non-positive number is returned, indicating the number of columns which were written before the error.

If a glyph can not fit in the current line, it is an error, unless scrolling is enabled.

Method: NcPlane.putnstr().
