I'd like to write some documentation for something & I'd like it to look current w/ msdn style documentation.... does anyone know of an html template suitable for documenting a software component? i suck @ making things look good w/ html and am hoping to find a dreamweaver template for such a purpose....
thanks!

Hi!
I have some public functions in my class that simply need to return a private variable. Is it a good way to use the "inline" statement?
And what is it actually for? When is it suitable to use it?
Could someone explain me or post a link where it is described well? The MSDN documentation didn't really help me.
Thanks in advance
Greg

No, that has nothing to do with it.
Gregor S. wrote:

The idea of inline is you tell the compiler that a function is so small that it should be written
'in place' where it is called, rather than written once and then called via function calls. You can consider it similar to a macro, in that you write it once, but it gets expanded 'in place' where-ever you call it. Big caveat coming though.....
Gregor S. wrote:

Whenever you have a very small function that you think will be called a lot and you want to improve performance.

There's a surprise  ) The M$ guys don't really know C++ that well, or at least that's what you'd think if you read MSDN for anything that is to do with the standard.
Speaking of which - the caveat. In the standard, inline is a SUGGESTION to the compiler, it is free to ignore you, and free to inline something itself if it feels it should. Therefore, there is almost no value in the inline keyword.

Thank you very much!
The only problem is: I didn't find caveat in my dictionary

I'm curious what suggestions you have for us regarding the documentation for inline?
"The compiler treats the inline expansion options and keywords as suggestions. There is no guarantee that functions will be inlined. You cannot force the compiler to inline a particular function, even with the __forceinline keyword."
It seems to me that the documentation is clear about inlining being a hint to the compiler. Reading further it discusses at length the Microsoft-specific extensions to inlining (__inline, __forceinline).

OK, I'm waving the white flag on this one. The Microsoft documentation on the STL is bloody awful, and it's on that basis that I presumed the original poster was right in saying the inline docs were not clear. On the face of it, it appears inline is documented pretty much the way I explained it....

We rewrote the STL documentation (and revamped the implementation of the library itself) for Visual C++ .NET 2002 specifically to address the "bloody awful"-ness of the 6.0 docs.
Is it still that terrible? Why? The docs aren't intended to teach the use of STL to a beginner, but most of our feedback says the docs are quite adequate for experienced developers.

I am aware of the legal hassles you guys had with your STL implimentation and from the brief chance I've had to use the new one, you've done a great job in fixing it up. I've never had a need to read the new docs though, I've used it only on a legacy app, I mainly code C# at home and we still use VC6 at work.
Nick Hodapp (MSFT) wrote:

I presume not, based on how good the actual STL implimentation seems to be.
Now if Microsoft would only pull it together and fix partial template specialisation ( and would Koenig namespace lookup be too much to ask for ? ). Do you have any idea when the pts is happening ?

Partial Template Specialization and a slew of other ANSI/ISO C++ conformance features are in the works. Stay tuned.

AFAIR the VC7.1 compiler update was promised for this summer I also talked to people who already use a pre-release version and told me they are quite happy with it (it compiles Blitz++ and Loki!).
Can you give us any estimation when this cool thing is shipped to waiting masses?
It would be the real reason to switch to VStudio.Net...

Nick - I've got a question about the STL documentation - not about the presentation (which seems OK - personally, it's just I haven't used it much compared to the VC6 docs), but a techie question that was raised in comp.lang.c++.moderated earlier today - the STL documentation for containers (vector, list etc) contains the following in the description for the end() method:
'If the container is empty, the result is undefined'
Is this actually true?! There's a requirement on containers in the C++ Standard that begin() == end() for empty containers - and that's what your implementation does... There's nothing on the Knowledge Base if it is an error in the docs...

Ah hah, this _is_ confusing! The documentation for vector::end() reads:
Return Value
A pointer to the end of the vector object. If the vector is empty, the result is undefined.
This entire statement is misleading and I'll submit it as a bug. The iterator of a std::vector is no longer the same as a pointer. But an empty vector does satisfy begin() == end(). In our implementation, end() actually points to 0 internally when the vector is empty.

Hadn't even picked up on the pointer bit  - hadn't realised that your vector (and string, for that matter) iterators weren't pointers any more - still, I had made the correct assumption that the docs were wrong, not the code  (but not before tracing through the code in the debugger).
BTW - I presume the bug report indicts the documentation for all the container types - as I said before, the statement about the results of end() being undefined for an empty container is made in the documentation for each and every container type<edit>but not the basic_string class - but then that's not totally one of the container family</edit>.

Well, you shouldn't be upset for bad feedbacks. We pay 1000s of dollars for your products each year and I think it is our right to complain about the things that we paid for. It is nothing personal. And also you get your rewards. You are the richest company. Don't be so agressive! If there is something that I do not like, i would surely complain about it.

 Nick was simply asking genuine questions in order to get feedback so he can tell his guys to make it better. Nick's job is to make sure we're happy with VC++, so the more feedback he can get the better.
I only wish he'd hang out in the forums *more*

That's OK - I figured it was just one of those situations where not being able to see the face of the other person makes it easy to misinterpret.

Inline tells the compiler that you would like to place the actual code of a function "inline" with the code you are calling it from instead of making a jump to a farther away location in memory. It may allow faster execution, but it requires more memory because multiple copies of the same code are used.
Functions that do a simple calculation or simply return a variable are good choices for inline. However, it may or may not be used for your public functions. It is an optional directive and the compiler decides whether to use it or not.

Also, you cannot use inline functions for callbacks (for an obvious reason), nor you can't inline functions that take a variable number of parameters.
my 2 cents 
Michel
It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Actually you can use inline functions for callback. In this case the compiler (if he decided to inline the thing at all) automatically creates a not-inlined version of the function.

To add to what the others have said, inline functions are also useful when you've got a class that's a minimal wrapper around some data (doesn't really do much with it but hold it together; this happens a lot when OOPing Win32 APIs...) and you want to be all nice and proper about it, so you make all data members private or protected. Instead of going to all the bother of writing out a separate CPP file with the access functions, since they're not going to be doing any validation or conversion anyway, just add them all to the header file as inline functions.
(oh yeah, no matter if you use the inline keyword or not, in order for the compiler to actually expand it, the function does have to be in the header file, or at least some file included where it's used.)

IMHO you shouldn't even bother worrying about it. The compiler will inline functions as part of its normal optimization when it sees that they are very short and fast.

Is there a way to control the order in which global objects are constructed?
I have a global debug object in my main module and a few global objects in another module that are getting constructed before the debug object.
