# Mu programs start at a function called 'main' with this signature:
|
|
# fn main args: (address array kernel-string) -> exit_status/ebx: int
|
|
# If your program doesn't need commandline arguments you can drop it:
|
|
# fn main -> exit_status/ebx: int
|
|
#
|
|
# Notice that the output must be in ebx, so that the exit() syscall can pick
|
|
# it up.
