Author: Olivier Cado , Nevrax France Date: 2000-2001 Definition at line 42 of file udp_sock.h. Constructor & Destructor Documentation NLNET::CUdpSock::CUdpSock (  bool    logging = true )    Constructor. Parameters: logging  Disable logging if the server socket object is used by the logging system, to avoid infinite recursion Definition at line 62 of file udp_sock.cpp. References NLNET::CSock::createSocket. Member Function Documentation void NLNET::CUdpSock::bind (  const CInetAddress &    addr )    Same as bind(uint16) but binds on a specified address/port (useful when the host has several addresses). Definition at line 86 of file udp_sock.cpp. References _Bound, NLNET::CSock::_LocalAddr, NLNET::CSock::_Sock, addr, nldebug, and value. void NLNET::CUdpSock::bind (  uint16    port )    Binds the socket to the specified port. Call bind() for an unreliable socket if the host acts as a server and expects to receive messages. If the host acts as a client, call directly sendTo(), in this case you need not bind the socket. Definition at line 74 of file udp_sock.cpp. References addr, and NLNET::CSock::setLocalAddress. bool NLNET::CUdpSock::receive (  uint8 *    buffer, uint32 &    len, bool    throw_exception = true )    Receives data from the peer. (blocking function) The socket must be pseudo-connected. Reimplemented from NLNET::CSock. Definition at line 156 of file udp_sock.cpp. References NLNET::CSock::_BytesReceived, NLNET::CSock::_Connected, NLNET::CSock::_RemoteAddr, NLNET::CSock::_Sock, nlassert, and nldebug. bool NLNET::CUdpSock::receivedFrom (  uint8 *    buffer, uint &    len, CInetAddress &    addr, bool    throw_exception = true )    Receives data and say who the sender is. (blocking function) The socket must have been bound before, by calling either bind() or sendTo(). Parameters: buffer  [in] Address of buffer len  [in/out] Requested length of buffer, and actual number of bytes received addr  [out] Address of sender Definition at line 183 of file udp_sock.cpp. References NLNET::CSock::_BytesReceived, NLNET::CSock::_Sock, addr, and nldebug. void NLNET::CUdpSock::sendTo (  const uint8 *    buffer, uint    len, const CInetAddress &    addr )    Sends data to the specified host (unreliable sockets only).
