 //! \brief The value for `EXC_MASK_ALL` appropriate for the operating system at
 //!     run time.
 //!
 //! The SDK’s definition of `EXC_MASK_ALL` has changed over time, with later
 //! versions containing more bits set than earlier versions. However, older
 //! kernels will reject exception masks that contain bits set that they don’t
 //! recognize. Calling this function will return a value for `EXC_MASK_ALL`
 //! appropriate for the system at run time.
 //!
 //! \note `EXC_MASK_ALL` does not include the value of `EXC_MASK_CRASH`.
+//!     Consumers that want `EXC_MASK_ALL` along with `EXC_MASK_CRASH` must use
+//!     ExcMaskAll() | `EXC_MASK_CRASH` explicitly.
 exception_mask_t ExcMaskAll();
