#define ip_current_header

(

)

(current_header)

Get the IP header of the current packet.

This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return nullptr otherwise.

#define ip_current_netif

(

)

(current_netif)

Get the interface that received the current packet.

This function must only be called from a receive callback (udp_recv, raw_recv, tcp_accept). It will return nullptr otherwise.
