14   Current process sends a 'sig' signal to 'task' process with
15   'info' siginfo. If 'info' is SEND_SIG_NOINFO or SEND_SIG_PRIV,
16   'info' is not a pointer and you can't access its field. Instead,
17   SEND_SIG_NOINFO means that si_code is SI_USER, and SEND_SIG_PRIV
18   means that si_code is SI_KERNEL.
