The possessive form of who is whose. What is the equivalent possessive form of which?
which has the same purpose as who as a placeholder in a secondary sentence, with the difference that who is for people and living beings while which is for inanimate objects (please correct me if wrong).
Example:
An image is read and sent to the function, which's output is displayed.
Here I have used an obscure word invention: which's in place of the word I am looking for. What is the correct word to plug in, if any? Compare with a similar who-sentence:
An gift is wrapped and sent to the Peter, whose reaction is recorded.
The equivalent word in my mother tongue Danish is hvis:
Et billede læses og sendes til funktionen, hvis output vises på skærmen.
