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
USE MPI
! or the older form: INCLUDE 'mpif.h'
MPI_ERROR_CLASS(ERRORCODE, ERRORCLASS, IERROR)
INTEGER ERRORCODE, ERRORCLASS, IERROR
Fortran 2008 Syntax
USE mpi_f08
MPI_Error_class(errorcode, errorclass, ierror)
INTEGER, INTENT(IN) :: errorcode
INTEGER, INTENT(OUT) :: errorclass
INTEGER, OPTIONAL, INTENT(OUT) :: 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++ func-
tions 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.
