Logging Mechanism in C++

[Avinash]

Hello
I want to do some debugging stuff for my C++ program.
I want to have some mechanism by which I can pring function names at
runtime.
like
void function ()
{
LogMessage();
}

This LogMessage function should automatically take filename ( which is
possible using __FILE__ and line number using __LINE__ )
but how to get function name at runtime.

Thanks in Advance.

I'm not sure whether this is compiler specific, but I have written a
debugging mechanism for VC++ compilers some time ago, and I remember I used
__FUNCTION__ to log which function I'm currently debugging.

That's not a standard preprocessor identifier (it's gcc, I think). As
of the new C standard, the equivalent there is __func__. I don't know
whether C++ is in the process of adopting that or not.

I used it with Microsoft Visual C++ 7. So it's probably not gcc specific,
but it may not be standard conformous either.
Does the C++ standard define any preprocessor makros at all? I thought that
would be a compiler/implementation thing.
