MPI_Error_string
Return a string for a given error code
Synopsis
#include "mpi.h"
int MPI_Error_string( int errorcode, char *string, int *resultlen )
Input Parameters
- errorcode
- Error code returned by an MPI routine or an MPI error class
Output Parameter
| string | Text that corresponds to the errorcode
|
| resultlen | 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.
