raw_remove() function

RAW PCB to be removed. The PCB is removed from the list of RAW PCB's and the data structure is freed from memory.

Send the raw IP packet to the given address. An IP header will be prepended to the packet, unless the RAW_FLAGS_HDRINCL flag is set on the PCB. In that case, the packet must include an IP header, which will then be sent as is.

Bind an RAW PCB to a specific netif. After calling this function, all packets received via this PCB are guaranteed to have come in via the specified netif, and all outgoing packets will go out via the specified netif. @see raw_disconnect()

Send the raw IP packet to the given address, using a particular outgoing netif and source IP address. An IP header will be prepended to the packet, unless the RAW_FLAGS_HDRINCL flag is set on the PCB. In that case, the packet must include an IP header, which will then be sent as is.

Send the raw IP packet to the address given by raw_connect()

Set the callback function for received packets that match the raw PCB's protocol and binding. The callback function MUST either - eat the packet by calling pbuf_free() and returning non-zero. The packet will not be passed to other raw PCBs or other protocol layers. - not free the packet, and return zero. The packet will be matched against further PCBs and/or forwarded to another protocol layers.

Bind a RAW PCB. @see raw_disconnect()

Connect an RAW PCB. This function is required by upper layers of lwip. Using the raw api you could use raw_sendto() instead This will associate the RAW PCB with the remote address. @see raw_disconnect() and raw_sendto()

Disconnect a RAW PCB.

Receive callback function for RAW netconns. Doesn't 'eat' the packet, only copies it and sends it to conn->recvmbox @see raw.h (struct raw_pcb.recv) for parameters and return value
