Poll a Socket for Available Data
See more Socket/SSL/TLS Examples
Demonstrates Socket.PollDataAvailable, which performs a nonblocking check for readable activity and returns whether data or another read-ready condition is present.
Background. This lets an application check for incoming data without blocking, for example in an event loop that services multiple tasks.
