[ENet-discuss] Sending a struct which contains a pointer to arbitrary data...

[Daniel Aquino]

Yea I just created a few different structs for my libraries internal usage.

In relation to serialization some of you might find this link usefull:
 www.leonerd.org.uk/code/libpack/

libpack pretty much gives c the familiar pack/unpack functions you see
in higher level languages...

Thanks.
