The NdisFreeRWLock function frees a read/write lock that was previously allocated with the NdisAllocateRWLock function.
- Lock [in]
A pointer to an opaque NDIS_RW_LOCK_EX variable that represents a lock. The caller can use this lock to gain write or read access to resources that are shared among non-ISR driver threads.
A driver must call the NdisReleaseRWLock function to release a read/write lock before it calls the NdisFreeRWLock function.
