Stupid C++ Question

[schizoid]

I'm retarded (or, rather, I'm a grad student who hasn't touched C++ in fer days) and I can't remember how to do the following:

I have this threaded zorch that has a couple of shared queues, along with send and recieve threads. The send threads pick things off the queue and send them etc. My problem is that the push and pop functions to access the queue (it's standard queue.h stuff, I didn't write them) take a char* as a parameter. I want to be able to push and pop a class object. Now, if I could just cast the thing to a char* that'd work, because (and i know this is crappy tecnique, but whatever) all the systems this thingee is running on have the same OS/compiler/etc so if I sent a class/struct over as plain text, I can just cast it back and everything is peachy.

But you can't just cast a random-ass class to a char*...but i know there has got to be a way to make it plain text so I can push it to the queue etc.

Any ideas (and don't shoot me if it's something super-easy)

Thanks.

Someone want to explain to me why this is the wrong forum but this isn't?

now let's not point fingers here.

The reason is because some members really don't care one way or another. But both threads should technically be in another forum. Software I think.


BTW: What is a zorch?

You need to either template the queue or modify the code to use your class type. No way around that if you want the queue to be handling classes and not primitives.

You want to use STL.

deque<classtype> que; //declare a double ended queue of type classtype

That's what Spaceman Spiff's gun does to aliens. I guess he's writing some sort of logic program to queue up enemies in the gun's memory and have it auto-aim/fire.

Oh yeah...STL. 2 semesters of "here's how you do it yourself" are still fresh in my mind, this semester they're showing us the easy way. 😀

It is good to know how to do it yourself, since STL is not perfect 🙂 It is damn good, but definatly not perfect.

A zorch is like a doohickus, or a veeblefetzer, or possibly a thingamabob.

I'll take slightly imperfect in return for having a templated double-ended queue waiting for me when I fire up vim. And don't get me started on writing a templated queue in C...that was wretched.
