I have a c function that requires me to pass a comm pointer to the function I converted the function using Clang.jl showed below function Comm(comm_handle) ccall((:Comm, librarypath), Cint, (Ptr{Cvoid}), comm_handle) end But I am getting an error if I pass MPI.MPI_COMM_WORLD to the function …

How can I pass the pointer of MPI communicator to c function?
