Convert an error handler from its c representation to its fortran representation
#include <mpi.h> MPI_Fint MPI_Errhandler_c2f(MPI_Errhandler err)
- C error handler
- Fortran error handler
This is a non-standard MPI routine. It is mainly here because ROMIO needs it.
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).
