 |
|
C99 defines the manifest constant __func__, which expands to the name
of the current function. The C++ Builder 4 documentation pretty
clearly indicates that neither __func__ nor the GNU version
__FUNCTION__ are supported. Is this manifest constant or an
equivalent present in later versions of C++ Builder?

C++ Builder provides __FILE__ and __LINE__ With them you not only
know the function, you know on which line within the function.

Yes, I know about those; they're fine for debugging, but for display
purposes the aforementioned __FUNC__ macros would be most desirable.

You have it. It's called __FUNC__. We use it in our error handler.

I've been told that it was introduced with C++ Builder 5;
unfortunately we are still using version 4.

This is not a part of C++. There was a proposal to add it to the next
version, although I have heard no feedback on that so it may have died.
Maybe we should push it ourselves <g> [I think this is a great
feature, as we use it ourselves]
If you are using the Boost libraries, you can use the Boost macro
BOOST_FUNCTION_NAME that expands the compiler-defined function-name
macro where avaiable, or an empty string literal otherwise. That's
what we use, even though most our code is only compiled under BCB.
