Hi!
The function MDSchemaCopyMetaAttributesForAttribute() is documented
to return a dictionary with the following keys:
const CFStringRef kMDAttributeName;
const CFStringRef kMDAttributeType;
const CFStringRef kMDAttributeMultiValued;
The kMDAttributeType leads to "A CFNumberRef or CFTypeId describing
the type of data returned as the value of the metadata attribute key."
What shall I make of this?
My understanding is that if I run into a CFTypeId then I may use
CFCopyTypeIDDescription() to investigate further. Though I don't know
what to expect.
What if I get a CFNumberRef? What does it mean?
TIA
Pierre Bernard
