According to [Apple documentation](https://opensource.apple.com/source/CF/CF-855.14/CFCalendar.h.auto.html) `CFCalendarGetIdentifier` must take a `CFCalendarRef` as an input parameter and return the calendar's identifier. But according core-foundation-sys, the docs states: ```rust pub unsafe extern "C" fn CFCalendarGetIdentifier( identifier: CFCalendarIdentifier ) -> CFCalendarIdentifier ``` Please have a look, I checked in the [repo](https://github.com/servo/core-foundation-rs/blob/6940925635f050a2c7dec9a777a3d3602cc7c2fb/core-foundation-sys/src/calendar.rs#L114C1-L115C1) Also this mismatch can also be found for: `CFCalendarCopyLocale` which should should take `CFCalendarCopyLocale` instead of `CFCalendarIdentifier`
