DDS15 — Definition of BuiltinTopicKey_t

  • Key: DDS15-153
  • Legacy Issue Number: 10581
  • Status: open  
  • Source: MilSOFT ( Ertan Deniz)
  • Summary:

    The PSM mapping of BuiltinTopicKey_t is defined to be as:

    struct BuiltinTopicKey_t { 

    But the DDS Interoperability Wire Protocol (RTPS) specifies that GUID consists of 12 bytes GuidPrefix and 4 bytes EntityId.

    In order to map GUID and BuiltinTopicKey, we should define BuiltinTopicKey as either

    typedef octet BuiltinTopicKey[16];

    or else if we really wanted to preserve the definition as an array of longs

    struct BuiltinTopicKey_t { 

    But the latter could cause problems due to different endianess unless we also specified how to place the octets that arrive at the protocol level into the array of long.
