man MPI_Type_f2c (Fonctions bibliothèques) - Convert a datatype handle from its Fortran representation to its C representation

NAME

MPI_Type_f2c - Convert a datatype handle from its Fortran representation to its C representation

SYNOPSIS

#include <mpi.h>
MPI_Datatype
MPI_Type_f2c(MPI_Fint f_handle)

INPUT PARAMETER

f_handle
- Fortran datatype handle

RETURN VALUE

datatype
- C datatype 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.
