Detailed Description

QoS bundle applied at DataWriter creation. §1.1b-B added the liveliness / deadline / lifespan fields alongside partitions.

§1.5 layout — this is an ABI-versioned struct; append-only. Consumers should always zero-init (AstuteDDS_DataWriterQos q = {0}; or use astutedds_default_datawriter_qos()).

Duration fields are nanoseconds; ASTUTEDDS_DURATION_INFINITE (or any negative value) means "infinite" per DDS §2.2.3. The partitions pointer + partition_count describe an array of null-terminated strings; the buffer is copied at create time and may be freed by the caller after return. partitions may be NULL when partition_count is 0.
