40  * input: stream of short; output: stream of short
41  *
42  * This is the inverse of gr::blocks::unpacked_to_packed_XX.
43  *
44  * The bits in the bytes or shorts input stream are grouped into
45  * chunks of \p bits_per_chunk bits and each resulting chunk is
46  * written right- justified to the output stream of bytes or
47  * shorts. All b or 16 bits of the each input bytes or short are
48  * processed. The right thing is done if bits_per_chunk is not a
49  * power of two.
50  *
51  * The combination of gr::blocks::packed_to_unpacked_XX_ followed by
52  * gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the
53  * general case of mapping from a stream of bytes or shorts into
54  * arbitrary float or complex symbols.
