38 * \brief Convert a stream of packed bytes or shorts to stream of unpacked bytes or shorts.
39 * \ingroup converter_blk
41 * input: stream of int; output: stream of int
43 * This is the inverse of gr_unpacked_to_packed_XX.
45 * The bits in the bytes or shorts input stream are grouped into chunks of
46 * \p bits_per_chunk bits and each resulting chunk is written right-
47 * justified to the output stream of bytes or shorts.
48 * All b or 16 bits of the each input bytes or short are processed.
49 * The right thing is done if bits_per_chunk is not a power of two.
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
54 * arbitrary float or complex symbols.
