Subject: Re: [Linux-streams] Re: [PATCH] Re: export of sys_call_tabl
Date: Thu, 10 Oct 2002 11:32:48 -0500 [thread overview]
Message-ID: <5.1.0.14.2.20021010113155.026a55f8@localhost> (raw)
Previous patch was "better" but not correct. How about this? (changed
return 0 to return ret).
int register_streams_calls(int (*putpmsg) (int, void *, void *, int, int),
int (*getpmsg) (int, void *, void *, int, int))
{
int ret = 0;
down_write(&streams_call_sem) ; /* should return int, but doesn't */
if ( (putpmsg != NULL && do_putpmsg != NULL)
|| (getpmsg != NULL && do_getpmsg != NULL)
)
ret = -EBUSY;
else {
do_putpmsg = putpmsg;
do_getpmsg = getpmsg;
}
up_write(&streams_call_sem);
return ret ;
}
