Hello,

In activex.pp, DebugServerQueryInterface is defined as follows:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i      
 Function DebugServerQueryInterface(CONST pv : Pointer):HResult;
StdCall;
In C/C++ the definition is:
Code: C  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i        
virtual HRESULT STDMETHODCALLTYPE DebugServerQueryInterface(         
 /* [annotation][out] */            _Outptr_  void **ppv) = 0; Note
that what is returned is a pointer to a pointer, not just a pointer as
the Pascal definition has it.  In addition to that, the parameter
cannot possibly be "const" since "pv" is where the value is returned.

More precisely, what's returned is a pointer to an interface.
