## Constructors

### StreamSocketImpl

StreamSocketImpl();

Creates a StreamSocketImpl.

### StreamSocketImpl

explicit StreamSocketImpl(
IPAddress::Family addressFamily
);

Creates a SocketImpl, with the underlying socket initialized for the given address family.

### StreamSocketImpl

StreamSocketImpl(
int sockfd
);

Creates a StreamSocketImpl using the given native socket.

## Destructor

### ~StreamSocketImpl

virtual ~StreamSocketImpl();

## Member Functions

### sendBytes

virtual int sendBytes(
const void * buffer,
int length,
int flags = 0
);

Ensures that all data in buffer is sent if the socket is blocking. In case of a non-blocking socket, sends as many bytes as possible.

Returns the number of bytes sent. The return value may also be negative to denote some special condition.
