Send a 32-bit Integer over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendInt32, which sends a value as a four-byte signed integer in the selected byte order.

Background. Fixed-size integers and length prefixes are common building blocks for application-defined binary protocols. Byte order is selectable, with big-endian being network byte order.
