Function speex_bits_peek_unsigned 

pub unsafe extern "C" fn speex_bits_peek_unsigned(
    bits: *mut SpeexBits,
    nbBits: c_int,
) -> c_uint

Same as speex_bits_unpack_unsigned, but without modifying the cursor position

@param bits Bit-stream to operate on @param nbBits Number of bits to look for @return Value of the bits peeked, interpreted as unsigned
