function _update_cache_set in Drupal 6

Same name and namespace in other branches

1. 7 modules/update/update.module \_update_cache_set()

Store data in the private update status cache table.

Note: this function completely ignores the {cache_update}.headers field since that is meaningless for the kinds of data we're caching.

Parameters

$cid: The cache ID to save the data with.

$data: The data to store.

$expire: One of the following values:

• CACHE_PERMANENT: Indicates that the item should never be removed except by explicitly using _update_cache_clear() or update_invalidate_cache().
• A Unix timestamp: Indicates that the item should be kept at least until the given time, after which it will be invalidated.
