       int sk_unattached_filter_create(struct sk_filter ** pfp, struct sock_fprog * fprog);

ARGUMENTS

       pfp
	   the unattached filter that is created

DESCRIPTION

       Create a filter independent of any socket. We first run some sanity checks on it to make sure it does not explode on us later. If an error
       occurs or there is insufficient memory for the filter a negative errno code is returned. On success the return is zero.
