MPI_Error_string

MPI_Error_string - Return a string for a given error code

SYNOPSIS
 

 
#include <mpi.h> 
int MPI_Error_string(int errcode, char *msg, 
       int *plen)

INPUT PARAMETERS

errcode
- Error code returned by an MPI routine or an MPI error class

OUTPUT PARAMETER

msg
- Text that corresponds to the errorcode
plen
- Length of string

NOTES

Error codes are the values return by MPI routines (in C) or in the ierr argument (in Fortran). These can be converted into error classes with the routine MPI_Error_class.


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.
