  • Forum Post: Re: What is an equivalent "NULL" value for MessageQ_QueueId?

    Shreyas Prasad
    Hi Eddie, MessageQ doesn't have an 'invalid queue id' value. I can think of two ways to get around your problem: 1) Let both tasks open the MessageQ. MessageQ_open will return a failure code (with a negative value) if the queue isn't available yet. 2) Let Task B pend on the 'msgqStatus'...

    Shreyas Prasad
    mans are there any major differences between IPC 1.2 to IPC 1.21 in this matter? No, the changes are very minor. Applications built with IPC 1.20 shouldn't require any changes to get them to work with IPC 1.21.
