Apc error detection

Question

The php documentation describes how apc_store functions return false if there is an error:

http://us3.php.net/manual/en/function.apc-store.php

I am curious what this means when there is an error, since I cannot find any functions to actually return what was the error, or any documentation about why it does not work and returns false.

Is there a php equivalent error_get_last for these return false apc functions? Or maybe error_get_last is exactly what I'm looking for?

thank

Edit: in fact, the documentation says it returns false on “failure”, although I'm not sure what that means
