Hi,

 I read about the CC3220 SDK source code and some things I don't understand，Mqueue. C in the SDK，Why is msg_len less than mq_msgsize return -1?

    This is part of the mq_receive() API definition. We are missing setting errno to EMSGSIZE, but returning -1 is the spec for this case.


    EMSGSIZE
    msg_len was less than the mq_msgsize attribute of the message
    queue.

    We are actively working on supplying errno values but do not have a time-frame yet.
