MPI_Op_c2f(3) LAM/MPI MPI_Op_c2f(3)NAME
MPI_Op_c2f - Convert an op handle from its C representation to its Fortran representation
SYNOPSIS
#include <mpi.h>
MPI_Fint
MPI_Op_c2f(MPI_Op op)
INPUT PARAMETER
op - C op handle
RETURN VALUE
f_handle
- Fortran op 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.
ERRORS
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.

documents contain detailed information about each MPI function (most of which is not duplicated in these man pages).
