Function IOPSCopyPowerSourcesList 

pub unsafe extern "C-unwind" fn IOPSCopyPowerSourcesList(
    blob: Option<&CFType>,
) -> Option<CFRetained<CFArray>>

Available on crate feature ps only.

Returns a CFArray of Power Source handles, each of type CFTypeRef.

The caller shouldn’t directly access the CFTypeRefs, but should use IOPSGetPowerSourceDescription on each member of the CFArrayRef.

Parameter blob: Takes the CFTypeRef returned by IOPSCopyPowerSourcesInfo()

Returns: Returns NULL if errors were encountered, otherwise a CFArray of CFTypeRefs. Caller must CFRelease() the returned CFArrayRef.

Safety

• blob should be of the correct type.
• blob might not allow None.
