It seems that the Address operator (&) works on all data types, but the dereference operator(*) only works on number pointers - Gah!

I want to call the Windows SDK function EnumDependentServicesA, which takes a pointer to an array of ENUM_SERVICE_STATUS structures (see below) and populates it.

typedef ENUM_SERVICE_STATUS
begin
   LPSTR   lpServiceName;
   LPSTR   lpDisplayName;
   SERVICE_STATUS ServiceStatus;
end;

Once the call completes, how do I dereference the LPSTR's to get the string values?


Thanks

There's a script on 'IS5/6 Samples>Strings' to convert pointers to strings, but if I'm not mistaken, you can just substitute 'STRING' for 'LPSTR', so

typedef ENUM_SERVICE_STATUS
begin
  STRING   lpServiceName;
  STRING   lpDisplayName;
  SERVICE_STATUS ServiceStatus;
end;

should work.
