Hi
I don't understand this line at all:
-----
explicit InterfaceQuery(FMSInterfaces iid) : interfaceId(iid),
itsInterface(0) {}
-----
as below. What exactly is that doing?
Many thanks
Michael

---------

enum FMSInterfaces {
FMSSystemInterface,
FMSDatabaseInterface,
FMSPadInterface,
FMSIRSInterface,
FMSPrefInterface
};

struct InterfaceQuery
{
explicit InterfaceQuery(FMSInterfaces iid) : interfaceId(iid),
itsInterface(0) {}

FMSInterfaces interfaceId;
void* itsInterface;
};

The same question was asked (and answered) once already today.
