Class encapsulating a TCP socket.
Definition: TcpSocket.h:25
Class defining a socket working in connected mode.
bool Connect(const unsigned int distantPort, const std::string distantAddress, Time timeout=0)
Returns a socket connected to a distant host.
ssize_t RecvMessage(char *buf, size_t buf_len, Time timeout=0)
Receive a message.
void Listen(const unsigned int port, const std::string localAddress="ANY")
Returns a socket which listens on a specific port/address.
uint16_t NetworkToHost16(uint16_t data)
! See Socket.h for a more generic implementation of network/host endianness
ssize_t SendMessage(const char *message, size_t message_len, Time timeout=0)
Send a message.
TcpSocket * Accept(Time timeout=0)
Returns a socket on a new incoming connexion.
