function hook_og_access_grants in Organic groups 6.2

Modify the policies put in place for group-based access control.

This hook allows easier modification and integration with OG Access by allowing manipulation of the node access grants defined by og_access_node_access_records(). hook_node_access_records() and the node grants system generally are advanced development topics and should not be attempted without background reading.

It is easily possible to destroy expected behaviors of OG access, or to extend OG Access to affect nodes not otherwise associated with OG.

Parameters

$grants: Array of grant arrays.

$node: A node object. Remember to test the node type to see if it is a group node, group post, or neither.
