The memcpy() function copies the entire struct layout to a buffer. You have to pass a pointer to the struct as the source argument, the buffer as the destination argument, and the size of the struct. If the struct in your code has pointers, handle them separately. Implementation C #inclu...

The INetworkSerializeByMemcpy interface is used to mark an unmanaged struct type as being trivially serializable over the network by directly copying the whole struct, byte-for-byte, as it appears in memory, into and out of the buffer. This can offer some benefits for performance compared to ...
