Receive a Block of Bytes to a File

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBytesToFile, which receives one available block of bytes and appends it to a file.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
