void * type cuda malloc does not work about cudart.jl

You can figure out why this happens by @which CUDArt.malloc( Void, 10 ) and then noticing that julia says sizeof(Void) is 0. Void is the type for nothing, and in julia it is literally...nothing.

Your best bet is to allocate with Int; using ccall I think you should be able to pass a Ptr{Int} directly as if it were a Ptr{Void}. You can also convert them if you want.

Thanks!, that was exactly my workaround; It only feels a bit awkward to allocate on one type and then convert to the other.

I guess a better way to do this would be to have a Cvoid (similar to Cint, Cfloat and so on) for this use case, but that is probably a discussion better suited for Julia.base.

Actually, now that I read more carefully you might be asking to allocate an array of void*? If so, that's CUDArt.malloc( Ptr{Void}, 10 ), which I think does what you want.

CUDArt.malloc( Ptr{Void}, 10 ) does the job. Thanks a lot!
