function block_list in Drupal 7

Same name and namespace in other branches

1. 4 modules/block.module \block_list()
2. 5 modules/block/block.module \block_list()
3. 6 modules/block/block.module \block_list()

Returns all blocks in the specified region for the current user.

@todo Now that the block table has a primary key, we should use that as the array key instead of MODULE_DELTA.

Parameters

$region: The name of a region.

Return value

An array of block objects, indexed with the module name and block delta concatenated with an underscore, thus: MODULE_DELTA. If you are displaying your blocks in one or two sidebars, you may check whether this array is empty to see how many columns are going to be displayed.
