Packets are referenced counted, so once you give it to enet_peer_send()
that increments its reference count by 1. It deletes when reference
count hits zero. Reference counts are decremented when the packet is
actually sent and no longer needed on that peer.
enet_packet_create() makes a copy of the data unless you use
ENET_PACKET_FLAG_NO_ALLOCATE, in which case there is no copy.
enet_peer_send() never copies anything, though, which was the claim.

Hi Lee,
really? I do
ENetPacket * packet =
enet_packet_create(p, pn, sendoptions);
ret = enet_peer_send(peer, channel,
packet);
and don't care about the packet or callbacks anyfurther. Also p is
deleted soon after. Maybe I'm wrong, but I thought the callback method
was added optionally. I also thought enet_packet_create copies the data.
How does it work otherwise?
Best regards
Marc

ENet does not copy the data at all. It simply queues the packet into a
list.
You need to use packet->freeCallback to see when it has deleted the
packet.

Hi Daniel,
I remember a discussing a while back about this. I think the current
behavior is when you call enet_peer_send it copies the data and you
can
immediately delete yours. Somehow you can change this, but I don't
remember how so it doesn't copy but instead calls the callback when
enet
doesn't need it anymore.
Best regards

nvm I found ENetPacket->freeCallback in the docs...

If I create a structure to send in the data of a packet.
Can I cleanup my data after calling enet_peer_send ?
