Function AEGetDescData 

Source 
pub unsafe extern "C-unwind" fn AEGetDescData(
    the_ae_desc: *const AEDesc,
    data_ptr: *mut c_void,
    maximum_size: c_long,
) -> i16
Available on crate feature AEDataModel only.
Expand description

The following calls are necessary to deal with opaque data in AEDescs, because the traditional way of dealing with a basic AEDesc has been to dereference the dataHandle directly. This is not supported under Carbon.

ยงSafety

  • the_ae_desc must be a valid pointer.
  • data_ptr must be a valid pointer.
