Does _msg_free() actually free the memory?

Hi,

I've a question regarding the _msg_free() api:

I've a situation where I've to do a malloc() of the message that I want to post on a message queue. My question is whether this memory is actually freed when I call the _msg_free() API?

Thanks in advance.

Regards,

sfarhan

You can't malloc a message. You must create a message pool, then allocate a message from the messag pool. _msg_free returns the message to the message pool. Read section 3.7.7.3 of the MQX users manual, it is explained there.
