FwpsDereferenceNetBufferList0 function (fwpsk.h)

Article
02/22/2024

The FwpsDereferenceNetBufferList0 function decrements the reference count for a NET_BUFFER_LIST structure that a callout driver had acquired earlier using the FwpsReferenceNetBufferList0 function.

Note FwpsDereferenceNetBufferList0 is a specific version of FwpsDereferenceNetBufferList. See WFP Version-Independent Names and Targeting Specific Versions of Windows for more information.

Syntax

void FwpsDereferenceNetBufferList0(
  [in, out] NET_BUFFER_LIST *netBufferList,
  [in]      BOOLEAN         dispatchLevel
);

Parameters

[in, out] netBufferList

A pointer to the NET_BUFFER_LIST structure for which the reference count is being decremented.

[in] dispatchLevel

A value that indicates that the current IRQL = DISPATCH_LEVEL. A callout driver should set this parameter to TRUE only if it is known that it is running at IRQL = DISPATCH_LEVEL. Otherwise a callout driver sets this parameter to FALSE.

Return value

None

Remarks

A callout driver calls the FwpsDereferenceNetBufferList0 function to decrement the reference count for a NET_BUFFER_LIST structure that it had acquired earlier using the FwpsReferenceNetBufferList0 function. A callout driver must not call the FwpsDereferenceNetBufferList0 function for a NET_BUFFER_LIST structure unless it previously called the FwpsReferenceNetBufferList0 for the same structure.
