) -> c_int

Write bits to the stream.

@param bs Bitstream handle @param v Bit mask. The n least significant bits of the mask are inserted in most significant to least significant order @param n Number of bits to extract from v into the stream

@return Number of bits written on success, negative errno value in case of error
