void argos::CTCPSocket::Accept

(

CTCPSocket &

c_socket

)

Accept a connection from a client.

Internally, the connection is forced to be only IPv4. Before calling this function, you must first call Listen() to setup connection listening.

Parameters

c_socket

The socket on which the connection has been created

Exceptions

CARGoSException

in case of error

See also

Listen

Connect

Definition at line 127 of file tcp_socket.cpp.

void argos::CTCPSocket::Connect	(	const std::string &	str_hostname,
		SInt32	n_port
	)

Connects this socket to the specified hostname and port.

Internally, the connection is forced to be only IPv4.

Parameters

str_hostname	The wanted hostname
n_port	The wanted port

Exceptions

CARGoSException

in case of error

Accept

Definition at line 32 of file tcp_socket.cpp.

void argos::CTCPSocket::Disconnect

(

)

Close the socket.

Exceptions

CARGoSException

in case of error

Definition at line 143 of file tcp_socket.cpp.

const std::string& argos::CTCPSocket::GetAddress ( ) const

inline

Returns a string containing the IPv4 address in dot notation.

Returns

A string containing the IPv4 address in dot notation.

Definition at line 41 of file tcp_socket.h.

int argos::CTCPSocket::GetStream ( ) const

inline

Returns the socket stream.

Returns

the socket stream.

Definition at line 33 of file tcp_socket.h.

bool argos::CTCPSocket::IsConnected ( ) const

inline

Returns true if the socket is connected.

Returns

true if the socket is connected.

Definition at line 25 of file tcp_socket.h.

void argos::CTCPSocket::Listen	(	SInt32	n_port,
		SInt32	n_queue_length = 10
	)

Listens for connections on the specified local port.

Internally, the connection is forced to be only IPv4. To actually accept connections, you must call Accept() after calling this function.

Parameters

n_port	The wanted port
n_queue_length	The maximum length of the queue of pending connections (also called the backlog)

Exceptions

CARGoSException

in case of error

bool argos::CTCPSocket::ReceiveBuffer	(	UInt8 *	pun_buffer,
		size_t	un_size
	)

Fills the passed buffer with the data received through the socket.

Parameters

pun_buffer	The buffer to fill
un_size	The size of the buffer

Returns

true if the buffer was filled correctly; false if the connection was closed by the other peer

Exceptions

CARGoSException

in case of error

Definition at line 169 of file tcp_socket.cpp.

bool argos::CTCPSocket::ReceiveByteArray

(

CByteArray &

c_byte_array

)

Receives the passed byte array through the socket.

Internally, this function first receives the size of the byte array as a long int, and then receives the content of the byte array. It is meant to the be used in conjunction with SendByteArray().

Parameters

c_byte_array

The byte array

Returns

true if the buffer was filled correctly; false if the connection was closed by the other peer

Exceptions

CARGoSException

in case of error

void argos::CTCPSocket::SendBuffer	(	const UInt8 *	pun_buffer,
		size_t	un_size
	)

Sends the passed buffer through the socket.

Parameters

pun_buffer	The wanted buffer
un_size	The size of the buffer

Exceptions

CARGoSException

in case of error

Definition at line 152 of file tcp_socket.cpp.

void argos::CTCPSocket::SendByteArray

(

const CByteArray &

c_byte_array

)

Sends the passed byte array through the socket.

Internally, this function first sends the size of the byte array as a long int, and then sends the content of the byte array. It is meant to the be used in conjunction with ReceiveByteArray().

Parameters

c_byte_array

The byte array
