Return value

array An associative requirements array as is returned by hook_requirements(). If the toolkit claims no requirements to the system, returns an empty array. The array can have arbitrary keys and they do not have to be prefixed by e.g. the module name or toolkit ID, as the system will make the keys globally unique.
