Detailed Description

Convert a stream of packed bytes or shorts to stream of unpacked bytes or shorts.

input: stream of unsigned char; output: stream of unsigned char

This is the inverse of gr::blocks::unpacked_to_packed_XX.

The bits in the bytes or shorts input stream are grouped into chunks of bits_per_chunk bits and each resulting chunk is written right- justified to the output stream of bytes or shorts. All b or 16 bits of the each input bytes or short are processed. The right thing is done if bits_per_chunk is not a power of two.

The combination of gr_packed_to_unpacked_XX_ followed by gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.
