MPI_Comm_f2c(3) LAM/MPI MPI_Comm_f2c(3)
MPI_Comm_f2c - Convert a communicator handle from its Fortran representation to its C representation
- Fortran communicator handle
comm - C communicator handle
NOTES FOR FORTRAN
All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK ) have an additional argument ierr at the end of the argument list. ierr
is an integer and has the same meaning as the return value of the routine in C. In Fortran, MPI routines are subroutines, and are invoked
with the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are of type INTEGER in Fortran.
This function does not return the normal MPI_SUCCESS integer value upon success. Instead, it returns a handle to the converted object. If
an error occurs, the appropriate NULL handle will be returned.
For more information, please see the official MPI Forum web site, which contains the text of both the MPI-1 and MPI-2 standards. These
documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
