In fact, this is currently being discussed in IRC:
[30 23:47] <timotimo> ah, yes, CArray of CStruct is an array of pointers to
structs
[30 23:47] <timotimo>
https://github.com/MoarVM/MoarVM/blob/master/src/6model/reprs/CArray.c#L53
- check these lines
[30 23:48] <sortiz> zwu, If you need to pass an inline array of CStructs to
C you can use NativeHelpers::CStruct, from NativeHelpers::Blob.
[30 23:48] <timotimo> nice
[30 23:49] <sortiz> See:
https://github.com/salortiz/NativeHelpers-Blob/blob/master/t/02-cstruct.t
[30 23:50] <timotimo> we might want to offer a deprecation cycle for CArray
of CStruct and ask users to use CArray[CPointer[type]] instead?
