NDK_EXTENSION_INTERFACE structure (ndkpi.h)

The NDK_EXTENSION_INTERFACE structure specifies dispatch function entry points for an NDK extension interface.

Syntax

typedef struct _NDK_EXTENSION_INTERFACE {
  const VOID *Dispatch;
} NDK_EXTENSION_INTERFACE;

Members

Dispatch

An entry point for an extension interface dispatch function.

Remarks

An extension interface is identified by a GUID and represented as a pointer to an NDK_EXTENSION_INTERFACE function dispatch table.

Each NDK object contains a NDK_FN_QUERY_EXTENSION_INTERFACE function pointer in its object type-specific function dispatch table. This function allows a driver to query the extended interfaces the object type supports.
