Member Function Documentation

int ACE_Log_Msg_IPC::close (  void    )  [virtual]

Close the backend completely. Implements ACE_Log_Msg_Backend. Definition at line 44 of file Log_Msg_IPC.cpp. References ACE_SOCK_Stream::close, and message_queue_. Referenced by reset, and ~ACE_Log_Msg_IPC. { return this->message_queue_.close (); }

int ACE_Log_Msg_IPC::log (  ACE_Log_Record &    log_record )  [virtual]

Backend routine. This is called when we want to log a message. Since this routine is pure virtual, it must be overwritten by the subclass. Implements ACE_Log_Msg_Backend. Definition at line 50 of file Log_Msg_IPC.cpp. References ACE_Log_Record::length, message_queue_, ACE_Log_Record::priority, ACE_SOCK_IO::send, and ACE_SOCK_Stream::send_n. { #if defined (ACE_HAS_STREAM_PIPES) ACE_Str_Buf log_msg (ACE_static_cast (void *, &log_record), ACE_static_cast (int, log_record.length ())); // Try to use the <putpmsg> API if possible in order to // ensure correct message queueing according to priority. return this->message_queue_.send (ACE_static_cast (const ACE_Str_Buf *, 0), &log_msg, ACE_static_cast (int, log_record.priority ()), MSG_BAND); #else // We're running over sockets, so we'll need to indicate the // number of bytes to send. return this->message_queue_.send_n ((void *) &log_record, log_record.length ()); #endif /* ACE_HAS_STREAM_PIPES */ }

int ACE_Log_Msg_IPC::open (  const ACE_TCHAR *    logger_key )  [virtual]

Open a new connection. Implements ACE_Log_Msg_Backend. Definition at line 19 of file Log_Msg_IPC.cpp. References ACE_TCHAR, and ACE_SOCK_Connector::connect. { ACE_LOG_MSG_IPC_CONNECTOR con; return con.connect (this->message_queue_, ACE_LOG_MSG_IPC_ADDR (logger_key)); }

int ACE_Log_Msg_IPC::reset (  void    )  [virtual]

Implements ACE_Log_Msg_Backend. Definition at line 27 of file Log_Msg_IPC.cpp. References close, ACE_IPC_SAP::get_handle, message_queue_, and ACE_SOCK_Stream::send_n. { if (this->message_queue_.get_handle () != ACE_INVALID_HANDLE) { // If we don't do this, handles aren't reused on Win32 and the // server eventually crashes! #if defined (ACE_WIN32) ACE_INT32 dummy = ~0; this->message_queue_.send_n ((const void *) &dummy, sizeof (ACE_INT32)); #endif /* ACE_WIN32 */ return this->close (); } return 0; }
