FILTER_EXTENSION structure (ntdddump.h)
The crash dump driver passes a pointer to a FILTER_EXTENSION structure when the filter driver callback routines are called.
Syntax
typedef struct _FILTER_EXTENSION {
FILTER_DUMP_TYPE DumpType;
PDEVICE_OBJECT DeviceObject;
DISK_GEOMETRY Geometry;
LARGE_INTEGER DiskSize;
DISK_PARTITION_INFO PartitionInfo;
PVOID DumpData;
ULONG Size;
ULONG Flags;
} FILTER_EXTENSION, *PFILTER_EXTENSION;
Members
DumpType
This parameter indicates the type of dump that this instance of the filter driver is loaded on.
