NAME
       bpf_prog_create - create an unattached filter

SYNOPSIS
       int bpf_prog_create(struct bpf_prog ** pfp, struct sock_fprog_kern * fprog);

ARGUMENTS
       pfp
           the unattached filter that is created

       fprog
           the filter program

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.
