Howdy Overflowites, I'm looking to see if anyone knows of a higher-resolution "Sleep" API than can be achieved using the following code block: ::timeBeginPeriod( 1 ); ::Sleep( 1 ); ::timeEndPeriod( 1 ); I'm trying to accomplish some "process balancing" work, and after some experimenting, find I need finer grain control than the...

What's the best practice for switch vs if for a 30 unsigned enumerations where about 10 have an expected action (that presently is the same action). Performance and space need to be considered but are not critical. I've abstracted the snippet so don't hate me for the naming conventions :p // numError is an error enumeration type, with...
I've found the standard hashing function on VS2005 is painfully slow when trying to achieve high performance look ups. What are some good examples of fast and efficient hashing algorithms that should void most collisions? ...
Here is a test case: void foo(int i, int j) { printf("%d %d", i, j); } ... test = 0; foo(test++, test); I would expect to get a "0 1" output, but I get "0 0" What gives?? ...
I'm looking for an extremely fast atof() implementation on IA32 optimized for US-en locale, ASCII, and non-scientific notation. The windows multithreaded CRT falls down miserably here as it checks for locale changes on every call to isdigit(). Our current best is derived from the best of perl + tcl's atof implementation, and outperform...
Can anyone point me to a library for 2D game physics, etc for programming gravity, jumping actions, etc for a 2d platform/sidescrolling game ? Or could you suggest some algorithms for side scroller like mario, sonic etc? ...
When asking about common undefined behavior in C, souls more enlightened than I referred to the strict aliasing rule. What are they talking about? ...
I understand that the function is not allowed to change the state of the object, but I thought I read somewhere that the compiler was allowed to assume that if the function was called with the same arguments, it would return the same value and thus could reuse a cached value if it was available. e.g. class object { int get_value(int...
How do I write a cpp macro which expands to include newlines? ...
We all know what virtual functions are in C++, but how are they implemented at a deep level? Can the vtable be modified or even directly accessed at runtime? Does the vtable exist for all classes, or only those that have at least one virtual function? Do abstract classes simply have a NULL for the function pointer of at least one ent...

In the application we have something about 30 types of objects that are created repeatedly. Some of them have long life (hours) some have short (miliseconds). Objects could be created in one thread and destroyed in another. Does anybody have any clue what could be good pooling technique in the sense of minimal creation/destruction l...

I am working with a very large code in C/C++. Indexing and referencing is a must in this environment. What tools would you recommend for viewing/browsing the code? Preferably open source.
