Determines whether the user has a global viewing grant for all nodes.

Checks to see whether any module grants global 'view' access to a user account; global 'view' access is encoded in the {node_access} table as a grant with nid=0. If no node access modules are enabled, node.module defines such a global 'view' access grant.

This function is called when a node listing query is tagged with 'node_access'; when this function returns TRUE, no node access joins are added to the query.

Parameters

$account: (optional) The user object for the user whose access is being checked. If omitted, the current user is used. Defaults to NULL.

Return value

TRUE if 'view' access to all nodes is granted, FALSE otherwise.
