DatagramSend: how to get notification about send completion

[altucor]

Hi! I need help with understand how to correctly cleanup buffers after sending data via DatagramSend. What is the correct way of doing that?

I traced a bit of internal API calls and can see that my send request in the end is wrapped in QUIC_SEND_REQUEST which is just appended to tail of existing events, seems like without copying. In result I cannot just free my buffer until it got processed by quic internals and I get some completion notification. Right now I'm getting dbg interrupt at QuicDatagramFrameEncodeEx when Buffers[i].Buffer is 0x00

I was expecting to find something similar to QUIC_STREAM_EVENT_SEND_COMPLETE, tried QUIC_CONNECTION_EVENT_DATAGRAM_SEND_STATE_CHANGED but didn't found my marker in Event->DATAGRAM_SEND_STATE_CHANGED.ClientContext.

Okay, it was my mistake, all is good. User specified context can be accessed at QUIC_CONNECTION_EVENT_DATAGRAM_SEND_STATE_CHANGED in field Event->DATAGRAM_SEND_STATE_CHANGED.ClientContext
