NF_STATUS nf_tcpPostReceive(ENDPOINT_ID id, const char * buf, int len)
NF_STATUS_SUCCESS on success, or other NF_STATUS error code on fail.
The library splits the buffer to packets and tries to indicate them to local socket. The method NF_EventHandler::tcpCanReceive is called when the internal packet buffer is empty. The function always returns NF_STATUS_SUCCESS after buffering the data. To optimize the usage of memory split large buffers to chunks and indicate each chunk after receiving tcpCanReceive. There is no need to wait for tcpCanReceive before indicating the first chunk.
If len is zero, the function sends a controlled disconnect request to local process for the specified TCP connection.
