void attribute
The base type void indicates a procedure with no arguments or a procedure that does not return a result value.
void function-name(parameter-list);
return-type function-name(void);
typedef [context_handle] void * context-handle-type;
return-type function-name(
[context_handle] void * * context-handle-type
, ...);
Parameters
-
function-name
-
Specifies the name of the remote procedure.
-
parameter-list
-
Specifies the list of parameters passed to the function along with the associated parameter types and parameter attributes.
-
return-type

Remarks
The pointer type void *, which in C describes a generic pointer that can be cast to represent any pointer type, is limited in MIDL to its use with the [context_handle] keyword.
Examples
void VoidFunc1(void);
HRESULT VoidFunc2([in, out] short s1);
typedef [context_handle] void * MY_CX_HNDL_TYPE;
HRESULT InitHandle([out] MY_CX_HNDL_TYPE * ppCxHndl);
