NAME

MPI_Op_f2c - Convert a FORTRAN MPI operation into a C MPI operation

SYNOPSIS

#include <mpi.h> 
MPI_Op MPI_Op_f2c(MPI_Fint op ); 
#include <pmpi.h> 
MPI_Op PMPI_Op_f2c(MPI_Fint op ); 

INPUT PARAMETER

op - operation handle from FORTRAN (handle)

RETURN VALUE

C operation handle (handle)

DESCRIPTION

The MPI_Op_f2c() function is used to convert a FORTRAN integer-sized operation handle op , into a C MPI_Op handle. This function will never raise an error.

Since this function is compiled inline for performance reasons, a profiler will not be able to hook it. (In this MPI implementation, the C and FORTRAN handles are identical for this type of handle.) PMPI_Op_f2c() is the profiling version of this function.
