00042      * This is the inverse of gr::blocks::packed_to_unpacked_XX.
00043      *
00044      * The low \p bits_per_chunk bits are extracted from each input
00045      * byte or short.  These bits are then packed densely into the
00046      * output bytes or shorts, such that all 8 or 16 bits of the
00047      * output bytes or shorts are filled with valid input bits.  The
00048      * right thing is done if bits_per_chunk is not a power of two.
00049      *
00050      * The combination of gr::blocks::packed_to_unpacked_XX followed by
00051      * gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the
00052      * general case of mapping from a stream of bytes or shorts into
00053      * arbitrary float or complex symbols.
