Can't understand the syntax

[turtail]

I have a problem to understand the following code. Can anybody please help me to understand it.

indication = MediumIndication::IDLE;
catIndication = bb->subscribe(this, &mi, getParentModule()->getId());

catRadioState = bb->subscribe(this, &cs, getParentModule()->getId());

catDroppedPacket = bb->getCategory(&droppedPacket);

Specially, in this "bb->subscribe(this, &mi, getParentModule()->getId());" part.

Thanks in advance.

It would help you showed the declarations. Without them we can only guess.

'MediumIndication', 'bb' are two Class, 'mi', 'cs' are object of a class, 'subcribe' is a function, 'getParentModule()', 'getId()' are functions. droppedPacket is also an object of a class. I hope it is now clear to you now. Thanking you.

Still not enough. Plus bb is a pointer to a class.

[turtail]

yes thats right 'bb' is a pointer of a class.
