** How do I break VS code into the debugger? **
<code>__debugbreak();</code>

** How do I set thread affinity under Windows? **
<code>
Where x is the processor ID (zero indexed):

SetThreadIdealProcessor(GetCurrentThread(), x)

Where x is hex bitmask of which processors the thread can run on (i.e. 0x1 is processor 1, 0x4 is processor 3):

SetThreadAffinityMask(GetCurrentThread(), x))

Ensure you have #define _WIN32_WINNT 0x0500 defined before including Windows.h
