How does the kernel get more than five parameters?
Currently... eax = function code ebx = first parameter ecx = second parameter edx = third parameter esi = fourth parameter edi = fifth parameter
Some functions like mmap() take 6 parameters! Does anybody know how these parameters get passed? I have an "ultra-light" 'C' runtime library I have been working on and, so-far, I've got everything up to mmap() (in syscall.h) (89 functions) working. I thought, maybe ebp was being used, but it doesn't seem to be the case.
Maybe after 5 functions, there is a parameter list passed by pointer???? I don't have a clue and I can figure out the code, it's really obscure...
