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)
- 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.
