function nodequeue_load_queues in Nodequeue 7.3

Same name and namespace in other branches

1. 5.2 nodequeue.module \nodequeue_load_queues()
2. 6.2 nodequeue.module \nodequeue_load_queues()
3. 7.2 nodequeue.module \nodequeue_load_queues()

Load an array of $queues.

This exists to provide a way of loading a bunch of queues with the fewest queries. Loading 5 queues results in only 4 queries, not 20. This also caches queues so that they don't get loaded repeatedly.

Parameters

$queue_names: An array of queue names to load.

$bypass_cache: Boolean value indicating whether to bypass the cache or not.
