NAME
MPI_Add_error_code - Creates a new error code associated with error-
class
SYNTAX
C Syntax
#include <mpi.h>
int MPI_Add_error_code(int errorclass, int *errorcode)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_ADD_ERROR_CODE(ERRORCLASS, ERRORCODE, IERROR)
INTEGER ERRORCLASS, ERRORCODE, IERROR
C++ Syntax
#include <mpi.h>
int MPI::Add_error_code(int errorclass, int* errorcode)
INPUT PARAMETER
errorclass MPI error class (integer).
OUTPUT PARAMETERS
errorcode Error code returned by an MPI routine or an MPI error
class (integer).
IERROR Fortran only: Error status (integer).
DESCRIPTION
Creates a new error code associated with errorclass and returns its
value in errorcode.
NOTES
No function is provided to free error codes, as it is not expected that
an application will create them in significant numbers.
The value returned is always greater than or equal to MPI_ERR_LASTCODE.
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.
