NdisInterlockedAddLargeStatistic (NDIS 5.1) function

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

NdisInterlockedAddLargeStatistic performs an interlocked addition of a ULONG increment value to a LARGE_INTEGER addend value.

Syntax

VOID NdisInterlockedAddLargeStatistic(
  _In_ PLARGE_INTEGER Addend,
  _In_ ULONG          Increment
);

Parameters

• Addend [in]
  Pointer to a LARGE_INTEGER value that is incremented by the value of Increment.

• Increment [in]
  Specifies a ULONG value that is added to the value to which Addend points.

Return value

None

Remarks

Functions that perform interlocked operations must not cause a page fault to occur. Neither their code nor any of the data they access can cause a page fault without bringing down the system.

NdisInterlockedAddLargeStatistic masks interrupts, and can be safely used to synchronize a driver's MiniportISR function with other driver code.
