MPI_Error_class - Converts an error code into an error class.
#include <mpi.h>
int MPI_Error_class(int errorcode, int *errorclass)
USE MPI
! or the older form: INCLUDE ’mpif.h’
MPI_ERROR_CLASS(ERRORCODE, ERRORCLASS, IERROR)

MPI_Error_class(errorcode, errorclass, ierror)
INTEGER, INTENT(IN) :: errorcode

INTEGER, OPTIONAL, INTENT(OUT) :: ierror
- errorcode
- Error code returned by an MPI routine.
- errorclass
- Error class associated with errorcode.
- IERROR
- Fortran
only: Error status (integer).
The function MPI_Error_class maps
each standard error code (error class) onto itself.
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.
