Detailed Description

an O2 message container

Note: This struct represents an O2 message that is stored on the heap. O2message is an alias for O2netmsg. At the o2n (network) abstraction, there is no O2msg_data type.

Note that O2messages are on the heap and can be allocated, scheduled, sent, and freed. In contrast, O2msg_data structures are contained within O2messages and are passed to method handlers, but cannot be allocated, scheduled, sent, or freed. They are always the data field of a containing O2message.
