	__AROS_LH1(void, AddSemaphore,

/*  SYNOPSIS */
	__AROS_LA(struct SignalSemaphore *, sigSem, A1),

/*  LOCATION */
	struct ExecBase *, SysBase, 100, Exec)

/*  FUNCTION
	Adds a semaphore to the system public semaphore list. Since the
	semaphore gets initialized by this function it must be free at
	this time. Also the ln_Name field must be set.

    INPUTS
	sigSem - Pointer to semaphore structure

    RESULT

    NOTES
	Semaphores are shared between the tasks that use them and must
	therefore lie in public (or at least shared) memory.
