Function creachadair_imath_sys::mp_int_to_string

pub unsafe extern "C" fn mp_int_to_string(
    z: mp_int,
    radix: mp_size,
    str_: *mut c_char,
    limit: c_int
) -> mp_result

Converts z to a zero-terminated string of characters in the specified radix, writing at most limit characters to str including the terminating NUL value. A leading - is used to indicate a negative value.

Returns MP_TRUNC if limit was to small to write all of z. Requires MP_MIN_RADIX <= radix <= MP_MAX_RADIX.
