Functions

Mainloop mode ("NO_SYS")
[lwIP]

Use this mode if you do not run an OS on your system. More...

Functions

void lwip_init (void)
 Initialize all modules.
err_t ip_input (struct pbuf *p, struct netif *inp)
 If both IP versions are enabled, this function can dispatch packets to the correct one.
err_t netif_input (struct pbuf *p, struct netif *inp)
 Forwards a received packet for input processing with ethernet_input() or ip_input() depending on netif flags.

Detailed Description

Use this mode if you do not run an OS on your system.

#define NO_SYS to 1. Feed incoming packets to netif->input(pbuf, netif) function from mainloop, *not* *from* *interrupt* *context*. You can allocate a Packet buffers (PBUF) in interrupt context and put them into a queue which is processed from mainloop.
Call sys_check_timeouts() periodically in the mainloop.
Porting: implement all functions in Time, Critical sections and Compiler/platform abstraction.
You can only use Callback-style APIs in this mode.
Sample code:

          err_t ip_input 
          (
          struct pbuf * 
           p, 
        

        

          
          
          struct netif * 
           inp 
        

        

          
          )
          
        

      







If both IP versions are enabled, this function can dispatch packets to the correct one. 


Don't call directly, pass to netif_add() and call netif->input().

          void lwip_init 
          (
          void 
           )
          
        

      







Initialize all modules. 


Use this in NO_SYS mode. Use tcpip_init() otherwise.

          err_t netif_input 
          (
          struct pbuf * 
           p, 
        

        

          
          
          struct netif * 
           inp 
        

        

          
          )
          
        

      







Forwards a received packet for input processing with ethernet_input() or ip_input() depending on netif flags. 


Don't call directly, pass to netif_add() and call netif->input(). Only works if the netif driver correctly sets NETIF_FLAG_ETHARP and/or NETIF_FLAG_ETHERNET flag!
