function dmemcache_flush in Memcache API and Integration 6

Same name and namespace in other branches

1. 5.2 dmemcache.inc \dmemcache_flush()
2. 5 dmemcache.inc \dmemcache_flush()
3. 7 dmemcache.inc \dmemcache_flush()

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.

Parameters

$bin The bin to flush. Note that this will flush all bins mapped to the same server: as $bin. There is no way at this time to empty just one bin.

Return value

Returns TRUE on success or FALSE on failure.
