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.

        // condition is present, and false when nothing is immediately available.
