I've been using the Boost libraries, and in Boost.Exception, I've noticed code like the following: #define BOOST_THROW_EXCEPTION(x) ::boost::throw_exception(x) Just out of curiosity: what is the purpose of the leading "::" before "boost::throw_exception(x)"? ...
In C++ (gcc,VS) is NULL considered the same as False. Or more importantly if in a logical statement what does NULL evaluate to. There were a number of other questions but none for C++ specifically. For some reason looping with a NULL control for(;;) just freezes up the program indicating that there is something other than a NULL placed...

This is the function that takes a buffer of 16-bit data and adds it to the deque void AVAudioBuffer::enqueue(int16_t* src, size_t num, double pts) { // Save current size of buffer size_t size = data_buffe...

I am looking forward to build an application that relies heavily on geographic data. The application will use HTML5's ability to get GPS data and will do computations such as finding the nearest street, finding the shortest path between 2 points, etc. I was thinking of using a platform such as Google Maps, so it will most likely be writ...
I have a library written in C and I have 2 applications written in C++ and C. This library is a communication library, so one of the API calls looks like this: int source_send( source_t* source, const char* data ); In the C app the code does something like this: source_t* source = source_create(); for( int i = 0; i < count; ++i ) ...
I'm wondering if there are any simple ways to link boost libraries (all or individual) via some entry like.... -lSDL_ttf The above links SDL's True Type Font library. Can this be done with boost? If so, I'm not sure what file I'm linking for to link. I'm currently using boost_1_40_0. If this isn't possible, or there are better ways t...

I'm tired of copy pasting the header into my cpp file then hacking at it until its in the correct form. Has anyone made a program to read a header file and make a corresponding cpp skeleton? Who else wishes D was older and more stable? We should strike C++ from the records!!!! Example class A { public: int DoSomething( int...

I've got a function that takes a pointer to a buffer, and the size of that buffer (via a pointer). If the buffer's not big enough, it returns an error value and sets the required length in the out-param: // FillBuffer is defined in another compilation unit (OBJ file). // Whole program optimization is off. int FillBuffer(__int_bcount_opt...
