Hi I have a simple binary protocol with socket client (

write socket ):
(int a =4) -> to binarybuffer with memcpy -> send

server side ( read socket ):
read -> binarybuffer ->copy to (int b) with memcpy.


the memcpy is unsafe.
and if a badguy send something else.
server crash because of memory leak.

how can safely serilize and deserlize a datatype in server ?

What you suggest?

memcpy definitely isn't unsafe because you have to determine the exact size of the data to copy
