The libuv is the latest git master version.
I have tracked the memory of the buffer and will free on send_cb, but in
the source of uv__udp_send, I found some "copy" fragment:
req->bufs = req->bufsml;
if (nbufs > ARRAY_SIZE(req->bufsml))
req->bufs = malloc(nbufs * sizeof(bufs[0]));
if (req->bufs == NULL)
return -ENOMEM;
memcpy(req->bufs, bufs, nbufs * sizeof(bufs[0]));
handle->send_queue_size += uv__count_bufs(req->bufs, req->nbufs);
handle->send_queue_count++;
QUEUE_INSERT_TAIL(&handle->write_queue, &req->queue);
uv__handle_start(handle);
It should be zero-copy, shouldn't it ?
I also wonder the same stuff when I calling uv_write.
Thanks for your consideration.
