NAME¶
bpf_prog_create - create an unattached filter
SYNOPSIS¶
int bpf_prog_create(struct bpf_prog ** pfp, struct sock_fprog_kern * fprog);
ARGUMENTS¶
struct bpf_prog ** pfp
the unattached filter that is created
struct sock_fprog_kern * fprog

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.
