mpi.any.source()

These constants are mainly used by mpi.send, mpi.recv, and mpi.probe. Different implementation of MPI may use different integers for MPI\_ANY\_SOURCE, MPI\_ANY\_TAG, and MPI\_PROC\_NULL. Hence one should use these functions instead real integers for MPI communications.

Each function returns an integer value.
