Function Documentation

L4_CV void l4_thread_longjmp	(	l4_threadid_t	thread,
		l4_thread_jmp_buf	env,
		int	val
	)

inter-thread longjmp

Parameters:

	thread	thread to apply the longjmp to
	env	jump buffer
	val	0: setjmp returns with 1
	val	!0: return value of setjmp

This function sets thread to the location obtained by its former l4_thread_setjump on env.

Note:

In contrast to longjmp(3), this function returns.
