NAME
MPI_Op_free - Frees a user-defined combination function handle.
SYNTAX
C Syntax #include <mpi.h> int MPI_Op_free(MPI_Op *op) Fortran Syntax INCLUDE 'mpif.h' MPI_OP_FREE(OP, IERROR) INTEGER OP, IERROR C++ Syntax #include <mpi.h> void Op::Free()
INPUT
/OUTPUT PARAMETER op Operation (handle).
OUTPUT PARAMETER
IERROR Fortran only: Error status (integer).
DESCRIPTION
Marks a user-defined reduction operation for deallocation and sets op to MPI_OP_NULL.
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.
