Hi Guys,

Quick question.
Does memmove ensure that there will be a NULL put after the last element in dest?
Correctness of pirq_guest_unbind, e.g., depends on it.

Thanks,
Himanshu

no, it copy only N bytes from SRC to DEST.

(if the Nth bytes of SRC is NULL then DEST will be NULL terminated as
well)

No, memmove does not do that. I think pirq_guest_bind/unbind are 
correct -- can you point out how you think they are broken?

  Thanks,
