MPIFortranCommToCComm

Converts a MPI_Comm represented int Fortran (as an integer) to a MPI_Comm in C.

Synopsis

int MPIFortranCommToCComm(int fcomm,MPI_Comm *comm)
Not collective

Input Parameter

fcomm -the Fortran MPI_Comm (an integer)

Output Parameter

comm -the C MPI_Comm

Notes

MPIFortranCommToCComm() must be called in a C/C++ routine. MPI 1 does not provide a standard for mapping between Fortran and C MPI communicators; this routine handles the mapping correctly on all machines.

Keywords
