If your using C then remember to prepend your functions with an
underscore

C printf becomes
ASM _printf

If you are using C++ then you will need to follow the name mangling 
rules (I think).

Arguments are passed to functions from left to right on the stack, so

in NASM (assuming int args)

[ESP+4] = first arg.
[ESP+8] = 2nd arg

on entry to your function.

Most return values go in EAX.  Floats probably go in ST(0) but I'm not sure.
