module PacketGen::Plugin
  class SMB
    # Common blocks used for unsupported SMB messages.

    # {Blocks} handles parameter block and data block. Parameter block is
    # composed of:
    # * a 8-bit {#word_count} field,
    # * a {#words} field, an array of +PacketGen::Types::Int16le+.
    # Data block is composed of:
    # * a little endian 16-bit {#byte_count} field,
    # * a {#bytes} field, an array of +PacketGen::Types::Int8+.
