Function RTReleaseSpinlock

RTReleaseSpinlock releases a previously locked spinlock:

UINT RTReleaseSpinlock(RTSpinlock * Lock);

Parameters

Lock

Pointer to the spinlock to release.

return Value

Zero on failure or non-zero when the spinlock has been released. The function will fail if the calling CPU has not locked the spinlock.

Unless flag RT_SPIN_NO_INTS_DISABLE has been specified, the interrupt enable state is restored to the state at the time the spinlock was locked.

A spinlock released with RTReleaseSpinlock must have been locked with function RTLockSpinlock, but not with RTLockSpinlockFast.
