This macro returns the base address of an instance of a structure of a specified type if it has the address of a member within the containing structure.
PCHAR CONTAINING_RECORD(PCHAR Address,TYPE Type,PCHAR Field);
Parameters
- Address
Pointer to a field in an instance of a structure of type Type. - Type
The name of the type of the structure whose base address is to be returned, for example, type IRP. - Field
The name of the field pointed to by Address contained in a structure of type Type.
Return Values
Returns a pointer to the base of the structure containing Field.
Remarks
This macro is called to determine the base address of a structure whose type is known when the caller has a pointer to a field inside such a structure. This macro is useful for symbolically accessing other fields in a structure of known type.
A driver that calls this macro can be running at any IRQ level as long, as the structure is resident. If a page fault might occur, callers must be at or below IRQ level APC_LEVEL.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Wdm.h or Ntddk.h.
