This came up in describing an input to a function:
A handle to the daemon who's name is desired.
(Daemon is a type of process on a system.)
Somehow, "who's" just doesn't seem right because it's not a who, but a what. Could one say "... the daemon what's name is desired"?
It is wrong, but not because a daemon is a thing rather than a person — "who's" doesn't indicate possession, it's a contraction of "who is". You need whose, which is a possessive pronoun and adjective, like his, hers, etc. So, just like you'd say "his name", you'd say "whose name", or "its name".
