Question

How can I read a uint from a connected socket directly without having to do any conversion.

Effectively, what is the D equivalent to read(sock, &four_byte_var, 4). I can’t seem to convert a uint to anything that the D standard library socket.receive(void[]) will accept.

Answer 1

You need to pass a slice that surrounds the variable:

uint n;
socket.receive((&n)[0..1]);

Note that this approach is endian-sensitive.
