Hi, Suppose a buffer has been allocated from global resources with pfring_zc_get_packet_handle(): Why does pfring_zc_pkt_buff_data() also need to know a queue handle? Is it possible to fill up the u_char* packet buffer of this resource without knowing the proper tx queue handle at this moment? Regards, Manuel

Hi Manuel
you can pass any queue handle, it is needed by the library just to know the cluster belonging to the pkt handle,
we use a queue because in inter-process application you do not have a cluster handle.
