InitializeSynchronizationBarrier function (synchapi.h)
Initializes a new synchronization barrier.
Syntax
BOOL InitializeSynchronizationBarrier(
[out] LPSYNCHRONIZATION_BARRIER lpBarrier,
[in] LONG lTotalThreads,
[in] LONG lSpinCount
);
Parameters
[out] lpBarrier
A pointer to the SYNCHRONIZATION_BARRIER structure to initialize. This is an opaque structure that should not be modified by applications.
[in] lTotalThreads
The maximum number of threads that can enter this barrier. After the maximum number of threads have entered the barrier, all threads continue.
[in] lSpinCount
The number of times an individual thread should spin while waiting for other threads to arrive at the barrier. If this parameter is -1, the thread spins 2000 times. If the thread exceeds lSpinCount, the thread blocks unless it called EnterSynchronizationBarrier with SYNCHRONIZATION_BARRIER_FLAGS_SPIN_ONLY.
Return value
TRUE if the barrier was successfully initialized. If the barrier was not successfully initialized, this function returns FALSE. Use GetLastError to get extended error information.
