RTOS/TMDSEVM6678: Using IPC

Tool/software: TI-RTOS

Hi
Is it possible to use MessageQ_get() as below If I use MessageQ_get() for receiving data:
The program doesn't wait forever on MessageQ_get() function.

I mean when the program runs the MessageQ_get() function, if the result data is received it must process it.

If the MessageQ_get() function has not received the data, the program must not waist time on  MessageQ_get() function and must check 
it again on the next time step.

Thanks

    Hi Dariush,

    I've forwarded this to the RTOS team. Their feedback should be posted here.

    Hi dariush,

    You can specify the timeout argument in MessageQ_get() to get unblocked function call. The timeout argument is maximum duration to wait for a message in microseconds.see the MessageQ_get() API description here:
    software-dl.ti.com/.../_message_q_8h.html

    -----------------
    If no message is available, it blocks on the synchronizer object until the synchronizer is signaled or a timeout occurs. The synchronizer is signaled, when Message_put is called on the MessageQ handle. If a timeout occurs, the msg is set to NULL and the status is MessageQ_E_TIMEOUT. If a timeout of zero is specified, the function returns immediately and if no message is available, the msg is set to NULL and the status is MessageQ_E_TIMEOUT. The MessageQ_E_UNBLOCKED status is return, if MessageQ_unblock is called on the MessageQ handle.
    ----------------
