I'm writing a network-related module for a larger project. It's cross-platform, and the Windows implementation uses Winsock2.
I'm having some trouble figuring out the best way to handle the need...

On a related note, would select() ever indicate that a socket is *both* in the error set and another set? I can't find documentation either way, but that appears to be happening and I'm not sure how...

I'm trying to test a class that checks sockets for writability. Most of the time sockets should always be writable unless their buffers are full, but it's my understanding that polling for...

UUIDs would be great, except that I don't think there's an easy way to generate them at compile time......
Another approach is to declare a function-local type everywhere I want a static, and use...

That's an interesting idea, but I'm not convinced it will work....if two files start with the same letter but have different second letters, then (assuming identical lines) you'd end up with the same...

I'm looking for a way to generate a program-wide unique value to use as a template parameter. Generating a unique value within a translation unit is pretty easy with __LINE__, but that doesn't ensure...

I have a bit of logic that needs to work in a variety of environments. In particular, though, it seems that the libstdc++ that shipped with gcc 4.4.3 has has_trivial_assign, while later versions...

Oh, and the strange thing is that if I look up C2960, I get an unrelated error from VS6. There doesn't appear to be any documentation of this error message.

I am trying to use extern templates in VS 2010.
In most cases, people use extern templates purely as an optimization, but in my case I actually need them for correctness; in the header, the type...

Note that <string> and <cstring> are not the same.
<cstring> is C++'s name for the old C <string.h>. It contains functions to operate on char*-style strings, like strcat, strcpy, etc.

Is there a way to detect whether or not a template type has a protected destructor?
I see there is std::is_destructible in C++11, but I can't tell if this will return true or false for the...

I believe I've worked it out. I did need a helper class to do the majority of the logic and keep the extra type hidden from the main interface.

I may have generalized my example code too much....in my case, the parameter pack is a list of values, not types. This is good in that it allows me to pass an additional type as the first argument,...

Let's say I have a variadic base class with a pure-virtual function per type:
template <typename ... Types>
template <typename T, typename ... Types>

Thanks, that's exactly what I needed!

Here's an interesting question I encountered. This isn't critical, but it would be "cool" to know how to accomplish it....
Let's say I have a variadic type A and a non-variadic type B:

I don't really like base_from_member much, although I can see how it could occasionally save the day. In this case, though, it's a matter of completely inverting the normal construction/destruction...

I have an AbstractAgent base class that manages a background thread. The actual work done in the background thread is accomplished through a pure virtual function call.
Here's the problem: because...

I suspect I need to add these to Derived:
After reviewing what I'm actually trying to do, though, I'm going to make Consumer a...

Let's say I have a templated base class:
template <typename Input>
void consume(Input input)
// do something

That's just what the rule is, I've never thought too hard about it.
I suppose one *could* argue that a namespace is merely a scope, and like all scopes it doesn't require a closing semicolon,...

the same thing that's going on here:
So what you're saying is that during overload resolution, exact matches are preferred over template matches, but template matches are preferred over base...

I'm trying to learn how to use variadic templates, and I decided a great example would be serializing a series of types into a stringstream:
// Send a fully constructed message.

gcc will do what you need.
I suggest you learn about virtualization environments such as qemu. They can greatly simplify the process of experimenting with OS-level functionality without...

Let's be careful not to confuse the issue. Even though that last example works, there is a semantic difference between a pointer and an array, and that example mixes their syntax. It should be...
