QLThumbnailRequestGetTypeID()

Declaration

func QLThumbnailRequestGetTypeID() -> CFTypeID

Return Value

The type identifier for the QLThumbnailRequest opaque type.

Discussion

Thread-safety: This function should be called in the same thread as the thumbnail request is made in; generally, this is the same thread in which the GenerateThumbnailForURL callback was invoked.
