Hello Guys, A quite simple question on the C API and use with Julia I want to interface Julia functions with an existing C library cLib. This library has a function(let’s call it cfunction) that creates a buffer and fills it with Cfloat. The issue is that for some (opaque) reasons, they cast the b…

It seems that ptr should be buff = Vector{Cfloat}(undef,N) ptr = Ref(Ptr{Cvoid}(pointer(buff))) ccall((:cfunction,cLib),Cvoid,(Ptr{Ptr{Cvoid}},),ptr)

C interface for void**
