NAME

ARGUMENTS

pfp

the unattached filter that is created

fprog

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.
