The maximum size string that may be supplied by the system is MPI_MAX_PORT_NAME..SH SUPPORTED INFO KEYSNone. .SH ERRORSAlmost 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..spBefore the error value is returned, the current MPI error handler iscalled. 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.  .SH SEE ALSOMPI_Comm_acceptMPI_Comm_connect.br' @(#)MPI_Open_port.3 1.20 06/03/09
