Functions

u8_t raw_input (struct pbuf *p, struct netif *inp)
 Determine if in incoming IP packet is covered by a RAW PCB and if so, pass it to a user-provided receive callback function.
err_t raw_bind (struct raw_pcb *pcb, const ip_addr_t *ipaddr)
 Bind a RAW PCB.
err_t raw_connect (struct raw_pcb *pcb, const ip_addr_t *ipaddr)
 Connect an RAW PCB.
void raw_recv (struct raw_pcb *pcb, raw_recv_fn recv, void *recv_arg)
 Set the callback function for received packets that match the raw PCB's protocol and binding.
err_t raw_sendto (struct raw_pcb *pcb, struct pbuf *p, const ip_addr_t *ipaddr)
 Send the raw IP packet to the given address.
err_t raw_send (struct raw_pcb *pcb, struct pbuf *p)
 Send the raw IP packet to the address given by raw_connect()
void raw_remove (struct raw_pcb *pcb)
 Remove an RAW PCB.
struct raw_pcbraw_new (u8_t proto)
 Create a RAW PCB.
struct raw_pcbraw_new_ip_type (u8_t type, u8_t proto)
 Create a RAW PCB for specific IP type.

Function Documentation

u8_t raw_input ( struct pbuf p,
struct netif inp 
)

Determine if in incoming IP packet is covered by a RAW PCB and if so, pass it to a user-provided receive callback function.

Given an incoming IP datagram (as a chain of pbufs) this function finds a corresponding RAW PCB and calls the corresponding receive callback function.

Parameters:
ppbuf to be demultiplexed to a RAW PCB.
inpnetwork interface on which the datagram was received.
Returns:
- 1 if the packet has been eaten by a RAW PCB receive callback function. The caller MAY NOT not reference the packet any longer, and MAY NOT call pbuf_free().
- 0 if packet is not eaten (pbuf is still referenced by the caller).
