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

41
*
42
* input: stream of int; output: stream of int
43
*
44
* This is the inverse of gr_unpacked_to_packed_XX.
45
*
46
* The bits in the bytes or shorts input stream are grouped into chunks of
47
* \p bits_per_chunk bits and each resulting chunk is written right-
48
* justified to the output stream of bytes or shorts.
49
* All b or 16 bits of the each input bytes or short are processed.
50
* The right thing is done if bits_per_chunk is not a power of two.
51
*
52
* The combination of gr_packed_to_unpacked_XX_ followed by
53
* gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the
54
* general case of mapping from a stream of bytes or shorts into
55
* arbitrary float or complex symbols.
