View the official Windows Driver Kit DDI referenceNo description available.
The ExInterlockedAddLargeStatistic routine performs an interlocked addition of a ULONG increment value to a LARGE_INTEGER variable.
Addend [in]A pointer to the LARGE_INTEGER variable that is incremented by the value of Increment.
Increment [in]Specifies a ULONG value that is added to the variable that Addend points to.
Support routines that do interlocked operations must not cause a page fault. Neither their code nor any of the data they access can cause a page fault without bringing down the system.
ExInterlockedAddLargeStatistic masks interrupts, and can be safely used to synchronize an ISR with other driver code.
ExInterlockedAddLargeStatistic runs at any IRQL. The storage for the Addend parameter must be resident at all IRQLs.
