The IoAdjustPagingPathCount routine increments or decrements a caller-supplied page-file counter as an atomic operation.
VOID IoAdjustPagingPathCount( _In_ PLONG Count, _In_ BOOLEAN Increment );
This routine is useful for maintaining a count of paging files on a device. The operating system notifies a driver that a paging file has been created on, or removed from, one of the driver's devices by sending an IRP. The IRP has the major code IRP_MJ_PNP and the minor code IRP_MN_DEVICE_USAGE_NOTIFICATION.
This routine can be used for other counters, such as counters for hibernation files or crash-dump files.
