This graph shows which files directly or indirectly include this file:

Namespaces
namespace	MPMA
Classes
class	MPMA::RWSleepLock
	ReaderWriter sleep-lock (re-entrant safe). Read locks don't block each other out, but Write locks are exclusive to all other locks. More...
class	MPMA::TakeRWSleepLock
	Used to lock/unlock a RWSleepLock automatically using scope. The lock is released on dustruction. More...
class	MPMA::MutexLock
	Mutex (re-entrant safe). More...
class	MPMA::TakeMutexLock
	Used to lock/unlock a MutexLock automatically using scope. The lock is released on dustruction. More...
class	MPMA::SpinLock
	Spinlock (NOT re-entrant safe) that reverts to a sleeplock on single cpu systems. If no lock-contention occurs, these is extremely little overhead in use. More...
class	MPMA::TakeSpinLock
	Used to lock/unlock a spinlock automatically using scope. The lock is released on destruction. More...
class	MPMA::BlockingObject
	An object that can be used to block a thread until another thread signals it to resume. More...
Functions
void	MPMA::AtomicIntInc (volatile unsigned int *pint)
	Atomically increments an integer.
void	MPMA::AtomicIntDec (volatile unsigned int *pint)
	Atomically decrements an integer.
int	MPMA::AtomicIntAdd (volatile int *pint, int addValue)
	Atomically adds one integer to another and returns the value of the original.
bool	MPMA::AtomicCompareExchange (volatile unsigned int *pInt, unsigned int expectedValue, unsigned int newValue, volatile unsigned int &outResultValue)
	Compares expectedValue with the value at pInt, and if they are the same, sets pInt to newValue and returns true with outResultValue set to newValue. If they are different then pInt is unaffected, and returns false with outResultValue set to the value that was found at pInt.
