How are vmargs accessed in the VM?

[Hajime Inoue]

I'm trying to figure out how vmargs (of type JavaVMInitArgs) is accessed
in the vm. I can see how in main.c arguments are taken from argv and put
into the vmargs structure, but I don't see how they are accessed from
outside the code (say from intrp?)  My guess is that the structure is
renamed somehow, but I don't see where.

Can anyone tell me how this is done? 

Thanks,
