Hello, at my actual project I’d like to use FreeRTOSrecv() in zero-copy mode. So I have to call FreeRTOSrecv() with the FREERTOSZEROCOPY – flag set , and later call a second time FreeRTOS_recv() with NULL-pointer and number of received bytes to flush the data from the stream. Due to the nature of TCP my expected data may come in more than one part from the socket. So two questins arose: 1. Do I have to flush each received part or can I do it in whole in one call, where the sum of bytes is given? 2. Can I expect the pointers given back from FreeRTOS_recv() form a contiguous buffer or may the the data be stored anywhere? If the second question is answered negative, I think that the zero-copy option is kind of useless in this situation because I have to copy all the data parts to a buffer to have contiguous data, which I need later to work on it. Am I wrong? Thankjs an regards Hannes
