function node_access_needs_rebuild

Toggles or reads the value of a flag for rebuilding the node access grants.

When the flag is set, a message is displayed to users with 'access administration pages' permission, pointing to the 'rebuild' confirm form. This can be used as an alternative to direct node_access_rebuild calls, allowing administrators to decide when they want to perform the actual (possibly time consuming) rebuild. When unsure if the current user is an administrator, node_access_rebuild() should be used instead.

Parameters

$rebuild: (optional) The boolean value to be written.

Return value

bool|NULL: The current value of the flag if no value was provided for $rebuild.
