Function yinput_binary 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn yinput_binary(
    buf: *const c_char,
    len: u32,
) -> YInput

Function constructor used to create a binary YInput cell of a specified length. This function doesn’t allocate any heap resources and doesn’t release any on its own, therefore its up to a caller to free resources once a structure is no longer needed.
