5 – 6: node_access_write_grants($node, $grants, $realm = NULL, $delete = TRUE)

This function will write a list of grants to the database, deleting any pre-existing grants. If a realm is provided, it will only delete grants from that realm, but it will always delete a grant from the 'all' realm. Modules which utilize node_access can use this function when doing mass updates due to widespread permission changes.

Параметры

$node The $node being written to. All that is necessary is that it contain a nid.

$grants A list of grants to write. Each grant is an array that must contain the following keys: realm, gid, grant_view, grant_update, grant_delete. The realm is specified by a particular module; the gid is as well, and is a module-defined id to define grant privileges. each grant_* field is a boolean value.

$realm If provided, only read/write grants for that realm.

$delete If false, do not delete records. This is only for optimization purposes, and assumes the caller has already performed a mass delete of some form.

node_access_acquire_grants in modules/node/node.module: This function will call module invoke to get a list of grants and then write them to the database. It is called at node save, and should be called by modules whenever something other than a node_save causes the permissions on a node to change.
