For even more sophisticated - use-cases of ACE_Log_Msg please see the - $ACE_ROOT/netsvcs/clients/Logger/ examples. - - * test_log_msg.cpp: This program tests various feature of the - Log_Msg facility. It opens a log file and writes some - messages using different log priorities and output stream. - - You can invoke the program with or without command - parameters. When invoked with any parameters like, - - ./Log_Msg foobar - - the log messages are direct to stdout (or, ostream in C++.) - In this case, the program simulates an error EWOULDBLOCK and - write an error log to stdout as, - - would block - op_status and errnum work! - - When invoked without any parameters, except does the same - test as above but logs to default log stream "stderr," the - program also demonstrates logging messages/errors with - different priority and changing the logging destination. A - sample output is, - - would block - op_status and errnum work! - 3.141600, hello = 10000 - 6.283200, world = 20000 - 6.283200, world = 20000 - 9.424800, world = 30000 - 12.566400, world = 40000 - 15.708000, world = 50000 - HEXDUMP 48 bytes - 01 00 00 00 02 00 00 00 04 00 00 00 08 00 00 00 ................ - 10 00 00 00 20 00 00 00 40 00 00 00 80 00 00 00 .... ...@....... - 00 01 00 00 00 02 00 00 00 04 00 00 00 08 00 00 ................ - ./Log_Msg.EXE: (2710), badname: Function not implemented - - In this test, there are two lines containing "world` = - 20000." That's because in the program, both stderr and - stdout are "turned on" for logging before writing this log - message. The line containing "world = 30000" is written to - stdout only. Rest of the lines are all to the stderr. You - can examine this behavior by redirecting stderr and stdout - to different files. - - The HEXDUMP output shows how to take an arbitrary object and - hexdump its content for debugging. Finally, the program - shows an ordinary use case of logging error messages using - the ACE_ERROR macro. - - If you look into the program, there is also a demonstration - showing how to disable certain priorities of error message - temporarily. - |
