Hello,

The BIND(C) was removed in the latest errata,

Correct. The place for BIND(C) is in the interface for the underlying C routine. At that level, the arguments are interoperable. Cheers, Bill

Hello, I have a naive question. MPI3 has Fortran binding in forms like this:

MPI_Send(buf, count, datatype, dest, tag, comm, ierror) BIND(C) TYPE(*), DIMENSION(..), INTENT(IN) :: buf INTEGER, INTENT(IN) :: count, dest, tag ...

So how to interpret BIND(C) here? Is it to say this interface is interoperable with C? But I find the interface arguments are not interoperable, e.g., INTEGER, instead of C_INT. Thank you.
