What kind of stuff can you do with system calls?
can you use other languages besides C or Assembly for system calls? Such as java or python?, i'm guessing no for most, but idk
Can you do system calls with windows/mac, or just linux/unix?

Thanks guys! I'm a complete newb, just curious about these things, thanks :]

The most common uses of system calls are to do things like read/write to files and start sub processes.

Yes. Java and Python have libraries for system calls or built in functions.

Windows has its own set of system calls. Mac probably has the same system calls as Linux since they are both posix systems.

gotchya thanks :]
