*
* This is the "zero-copy receive" version of the MCC receive function. No data is copied.
* Only the pointer to the data is returned. This version is fast, but it requires the user to manage
* buffer allocation. Specifically, the user must decide when a buffer is no longer in use and
* make the appropriate API call to free it.
*
* \param[in] endpoint Pointer to the receiving endpoint to receive from.
* \param[out] buffer_p Pointer to the MCC buffer of the shared memory where the received data is stored.
* \param[out] recv_size Pointer to an MCC_MEM_SIZE that will contain the number of valid bytes in the buffer.
* \param[in] timeout_us Timeout, in microseconds, to wait for a free buffer. A value of 0 means don't wait (non-blocking call). A value of 0xffffffff means wait forever (blocking call).
*
* \return MCC_SUCCESS
