No error indication results ifthe operation successfully completes before IBSTOP is called.Board IBSTOP Function:If BD% specifies a board, IBSTOP attempts to terminate any unfinishedasynchronous I/O operation that had been started with a board functionusing that board.If the operation is aborted before completion, the ERR bit in the statusword is set and an EABO error is returned.
