NAME
MPI_Errhandler_free - Frees an MPI-style error handler.SYNTAX
C Syntax
#include <mpi.h> int MPI_Errhandler_free(MPI_Errhandler *errhandler)
Fortran Syntax
INCLUDE 'mpif.h' MPI_ERRHANDLER_FREE(ERRHANDLER, IERROR) INTEGER ERRHANDLER, IERROR
C++ Syntax
#include <mpi.h> void Errhandler::Free()
INPUT PARAMETER
- errhandler
- MPI error handler (handle). Set to MPI_ERRHANDLER_NULL on exit.
OUTPUT PARAMETER
- IERROR
- Fortran only: Error status (integer).
DESCRIPTION
Marks the error handler associated with errhandler for deallocation and sets errhandler to MPI_ERRHANDLER_NULL. The error handler will be deallocated after all communicators associated with it have been deallocated.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.
