Constructor & Destructor Documentation

industrial::simple_socket::SimpleSocket::SimpleSocket ( ) [inline]

Constructor.

Definition at line 147 of file simple_socket.h.

virtual industrial::simple_socket::SimpleSocket::~SimpleSocket ( ) [inline, virtual]

Destructor.

Definition at line 157 of file simple_socket.h.

Member Function Documentation

industrial::simple_socket::SimpleSocket::__attribute__ ( (deprecated("Please use: logSocketError(const char* msg, const int rc, const int error_no)")) ) const [protected]

Logs message to error log and reports associated socket system error.

Deprecated:: This could report the wrong error number. The method that takes errno as an argument should be used instead.

Parameters:

msg	custom message prefixed to system error
rc	return code from socket

int industrial::simple_socket::SimpleSocket::getSockHandle ( ) const [inline, protected]

Definition at line 224 of file simple_socket.h.

bool industrial::simple_socket::SimpleSocket::isConnected ( ) [inline, virtual]

return connection status

Returns:: true if connected

Implements industrial::smpl_msg_connection::SmplMsgConnection.

Definition at line 159 of file simple_socket.h.

bool industrial::simple_socket::SimpleSocket::isReadyReceive ( int timeout ) [inline]

returns true if socket data is ready to receive

Parameters:

timeout (ms) negative or zero values result in blocking

Returns:: true if data is ready to recieve

Definition at line 179 of file simple_socket.h.

virtual bool industrial::simple_socket::SimpleSocket::rawPoll	(	int	timeout,
		bool &	ready,
		bool &	error
	)		`[protected, pure virtual]`

polls socket for data or error

Parameters:

timeout	(ms) negative or zero values result in blocking
ready	true if ready
except	true if exception

Returns:: true if function DID NOT timeout (must check flags)

Implemented in industrial::udp_socket::UdpSocket, and industrial::tcp_socket::TcpSocket.

virtual int industrial::simple_socket::SimpleSocket::rawReceiveBytes	(	char *	buffer,
		industrial::shared_types::shared_int	num_bytes
	)		`[protected, pure virtual]`

Implemented in industrial::udp_socket::UdpSocket, and industrial::tcp_socket::TcpSocket.

virtual int industrial::simple_socket::SimpleSocket::rawSendBytes	(	char *	buffer,
		industrial::shared_types::shared_int	num_bytes
	)		`[protected, pure virtual]`

Implemented in industrial::udp_socket::UdpSocket, and industrial::tcp_socket::TcpSocket.

bool industrial::simple_socket::SimpleSocket::receiveBytes	(	industrial::byte_array::ByteArray &	buffer,
		industrial::shared_types::shared_int	num_bytes
	)		`[protected, virtual]`

Method used by receive message interface method. This should be overridden for the specific connection type.

Parameters:

data	to receive.
size	(in bytes) of data to receive

Returns:: true if successful

Implements industrial::smpl_msg_connection::SmplMsgConnection.

Reimplemented in TestServer.
