Interface Definition Language (IDL)

Interface definition language (IDL) files are a structured way to define interfaces and objects.

ex:

[

object,

uuid(),

helpstring("IWDFObject Interface"),

local,

restricted,

pointer_default(unique)

]

interface IWDFObject : IUnknown

{

HRESULT

DeleteWdfObject(

void

);

HRESULT

AssignContext(

[in, unique, annotation("__in_opt")] IObjectCleanup * pCleanupCallback,

[in, unique, annotation("__in_opt")] void * pContext

);

HRESULT

RetrieveContext(

[out, annotation("__out")] void ** ppvContext

);

void

AcquireLock(

void

);

void

ReleaseLock(

void

);

};
