function node_access_needs_rebuild

Flags or unflags the node access grants for rebuilding.

If the argument isn't specified, the current value of the flag is returned. 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.


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

Return value

The current value of the flag if no value was provided for $rebuild.
