php - Does anyone know if xcache functions are atomic?


I'm wondering which xcache functions are atomic. I know thatxcache_inc() andxcache_dec() are both atomic. I dont know ifxcache_get() andxcache_unset() are atomic.




The Feature List says that XCache supports "atomic get/set/inc/dec".

Soget is atomic, whatever that means. (It probably just means thatget never returns an in-between value, which is more or less the same thing as atomicset.)

Also, sinceset is atomic, I see no reason whyunset wouldn't be atomic, too.
