Insert bits into the compressed output stream.

    int bits,
    int value,
    error_code& ec);

This function inserts bits in the deflate output stream. The intent is that this function is used to start off the deflate output with the bits leftover from a previous deflate stream when appending to it. As such, this function can only be used for raw deflate, and must be used before the first write call after an initialization. bits must be less than or equal to 16, and that many of the least significant bits of value will be inserted in the output.

Return Value

error::need_buffers if there was not enough room in the internal buffer to insert the bits.
