Interface RawConn

Control invokes f on the underlying connection's file descriptor or handle. The file descriptor fd is guaranteed to remain valid while f executes but not after f returns.

Read invokes f on the underlying connection's file descriptor or handle; f is expected to try to read from the file descriptor. If f returns true, Read returns. Otherwise Read blocks waiting for the connection to be ready for reading and tries again repeatedly. The file descriptor is guaranteed to remain valid while f executes but not after f returns.

Write is like Read but for writing.
