Doesn't your compiler give these details already? Whe it encounters and error, the error message usually contains the line number and in some cases the code block/function name. Perhaps you need to explain better what is it that you're after.Danny at 2007-11-11 21:01:36 >

I'm going to guess that you are creating a macro that will allow you to write a message to a log file. Use the __LINE__ to capture the line number where the macro is expanded. Just a heads up you can get the current file name using __FILE__. These are ANSI compliant predefined macros.Cheers,

the function's name can be obtained by using the __func__ or __FUNCTION__ name. However, this is less standardized so every vendor has its own symbol.Danny at 2007-11-11 21:03:40 >
