* \brief Convert a stream of unpacked bytes or shorts into a stream of packed bytes or shorts.

* input: stream of int; output: stream of int
43
*
44
* This is the inverse of gr_packed_to_unpacked_XX.
45
*
46
* The low \p bits_per_chunk bits are extracted from each input byte or short.
47
* These bits are then packed densely into the output bytes or shorts, such that
48
* all 8 or 16 bits of the output bytes or shorts are filled with valid input bits.
49
* The right thing is done if bits_per_chunk is not a power of two.
50
*
51
* The combination of gr_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 arbitrary float
54
* or complex symbols.
