what is your favorite function, whether its in C C++ assembly, or whether u made it. the function you use the most that your os or any of your development could not live without. or a function that you use alot. leave a name, but NO SOURCE CODE to that function. (duh) but if you want, tell what it does.


my favorite is the 16 bit assembly made print function, the first function i ever used the most



(Sorry if this is a pointless thread)

BlpDisplayString. Its basically printf() and works the same way but using the BIOS. Without it some of the libraries in my system would have been far more harder to debug. Other then that my io_services(), which is like a protected mode int86() routine that my boot programs use.

(This seems kind of a pointless thread...)

My favorite function is probably the WinSock connect() function.

i like my cli function. i made it real efficient

get_next_task()

-JL

hack_the_gibson()

On a more serious note, probably memclr().

TcpManager::receive - handler for all incoming TCP packets. It may not be perfect, but I still love reading it

kitchen_sink()

More like kitchen_sync()! Ahahahahaha!

More seriously though...I have changed my mind. Instead, it is oh_noes()! <--is my debug function.

-JL

objc_msgSend(), because so much relies on it.

I'd go for something like VFS_Open()
It is a thing of beauty (until you see it's helpers )

Mine is definitely printf(), couldn't imagine debugging without it

operator<<() because it's awesome. It can be like printf++.

display << "Hello World " << worldNumber << "!";

worldNumber can be an int, float, short, or class that implements it's own operator<< and changing between them is as easy as changing the declaration and making sure there's an operator<< for the type you want. You don't have to go through and change every %i to %f or whatever and risk changing the wrong one.

I don't mean to make a pointless post, but I really want to say:

Firestryke31++;

Nothing better than being able to transparently handle output on a variety of user-defined classes without anything more than a simple operator overload.

Apart from that:
memoryTrib::memoryTrib();

Because my memory manager was the absolute most challenging thing in my OS, and having almost perfectly completed it, I get a sense of accomplishment knowing I did it without following any tutorials, or copying code from anywhere. *Shrug*. And it's completely SMP safe

That's the best part.

void *mm_alloc(size_t size);

I cannot imagine my os without this
