ReturnCode

A ReturnCode identify the various errors that may occur in different use cases of each interface. We have identified two types of ReturnCodes in two distinct namespaces: application-global ReturnCodes and DDS namespace-specific ReturnCodes.

In this document, we will only provide details on the ReturnCodes in the DDS layer since they represent the possible errors that can occur during the use of the DDS Layer:
