6 calls to dmemcache_stats_init()

dmemcache_add in ./dmemcache.inc

Add an item into memcache

dmemcache_delete in ./dmemcache.inc

Deletes an item from the cache.

dmemcache_flush in ./dmemcache.inc

Immediately invalidates all existing items. dmemcache_flush doesn't actually free any resources, it only marks all the items as expired, so occupied memory will be overwritten by new items.
