xQueueReceive example conflict

Posted by alsaleem on July 17, 2016

Hi,

I was viewing the xQueueReceive example in web-site (http://www.freertos.org/a00118.html).

The code for (vADifferentTask) makes a pointer to struct AMessage *pxRxedMessage

The description for this function says :

pvBuffer

Pointer to the buffer into which the received item will be copied

So, when calling this function, is it supposed to copy the message to my buffer or will provide a pointer to it?

There is a conflict here. I assume queue item will be deleted after call finishes, correct?

Thanks

Ahmad.

The parameter is a pointer to the buffer, often expressed as &buffer (where buffer is the buffer to put the data into). Note that you tend to pass buffers to functions by actually passing their address as a pointer.
