function module_grants_by_module in Module Grants 7

Return a map, keyed by module name, of grant arrays (keys are realms, values are array of grants) associated with the module, as returned by that module's hook_node_grants().

This is similar to node.module's node_access_grants(), but returns the grants by module instead of all at once.

Parameters

$op: The operation, i.e 'view', 'update' or 'delete'

$account: User account object

$nid: Optional. If passed in, only modules with at least one row in the node_acces table for the supplied nid are included (lenient interpretation of absence of node grants). If not passed in, then all modules implementing hook_node_grants() will be included (strict).

Return value

An array of module grants, keyed by module name. If a module implements hook_node_grants but didn't return any grants for this op/account/node, we still return it as a key with empty array as value.
