MPI_Error_class(3OpenMPI)                                                          MPI_Error_class(3OpenMPI)



NAME
       MPI_Error_class  - Converts an error code into an error class.


SYNTAX
C Syntax
       #include <mpi.h>
       int MPI_Error_class(int errorcode, int *errorclass)


Fortran Syntax
       INCLUDE 'mpif.h'
       MPI_ERROR_CLASS(ERRORCODE, ERRORCLASS, IERROR)
            INTEGER   ERRORCODE, ERRORCLASS, IERROR


C++ Syntax
       #include <mpi.h>
       int Get_error_class(int errorcode)


INPUT PARAMETER
       errorcode Error code returned by an MPI routine.


OUTPUT PARAMETERS
       errorclass
                 Error class associated with errorcode.

       IERROR    Fortran only: Error status (integer).


DESCRIPTION
       The function MPI_Error_class maps each standard error code (error class) onto itself.


ERRORS
       Almost  all  MPI  routines return an error value; C routines as the value of the function and Fortran
       routines in the last argument. C++ functions do not return errors. If the default  error  handler  is
       set  to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism will be used to throw
       an MPI:Exception object.

       Before the error value is returned, the current MPI error handler is called. By default,  this  error
       handler  aborts  the  MPI  job, except for I/O function errors. The error handler may be changed with
       MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used  to  cause  error
       values  to  be  returned.  Note  that MPI does not guarantee that an MPI program can continue past an
       error.
