NDK_OBJECT_HEADER structure (ndkpi.h)

The NDK_OBJECT_HEADER structure specifies the object version, type, and other information.

It is used in the Header member of every NDK object.

Syntax

typedef struct _NDK_OBJECT_HEADER {
  NDK_VERSION                      Version;
  NDK_OBJECT_TYPE                  ObjectType;
  NDK_OBJECT_HEADER_RESERVED_BLOCK NdkReserved;
} NDK_OBJECT_HEADER;

Members

Version

An NDK_VERSION structure that contains the revision number of the NDK object.

ObjectType

An NDK_OBJECT_TYPE enumeration value that specifies the NDK object type. You can use this member to identify an NDK object's type in a memory dump.

This member is required and cannot be zero.

NdkReserved

A reserved block in an NDK_OBJECT_HEADER_RESERVED_BLOCK structure.

Remarks

When an NDK provider creates an NDK object instance, the Header member must be initialized as follows:

• For Windows Server 2012, set the Version member to 1.1. To do this, set both the Major and Minor members of the NDK_VERSION structure to 1.
• For Windows Server 2012 R2, set the Version member to 1.2. To do this, set the Major member of the NDK_VERSION structure to 1 and the Minor member to 2.
• Set the ObjectType member to an NDK_OBJECT_TYPE value.
• Set the NdkReserved member to zero. The NDK provider must not modify this member until the object is closed.
