Function Documentation

err_t mem_free_callback (  void *  m  )

A simple wrapper function that allows you to free heap memory from interrupt context. Parameters: m  the heap memory to free Returns: ERR_OK if callback could be enqueued, an err_t if not

err_t pbuf_free_callback (  struct pbuf *  p  )

A simple wrapper function that allows you to free a pbuf from interrupt context. Parameters: p  The pbuf (chain) to be dereferenced. Returns: ERR_OK if callback could be enqueued, an err_t if not

err_t tcpip_callback_with_block (  tcpip_callback_fn  function, void *  ctx, u8_t  block )

Call a specific function in the thread context of tcpip_thread for easy access synchronization. A function called in that way may access lwIP core code without fearing concurrent access. Parameters: f  the function to call ctx  parameter passed to f block  1 to block until the request is posted, 0 to non-blocking mode Returns: ERR_OK if the function was called, another err_t if not

void tcpip_init (  tcpip_init_done_fn  initfunc, void *  arg )

Initialize this module: initialize all sub modules start the tcpip_thread Parameters: initfunc  a function to call when tcpip_thread is running and finished initializing arg  argument to pass to initfunc

err_t tcpip_input (  struct pbuf *  p, struct netif *  inp )

Pass a received packet to tcpip_thread for input processing Parameters: p  the received packet, p->payload pointing to the Ethernet header or to an IP header (if inp doesn't have NETIF_FLAG_ETHARP or NETIF_FLAG_ETHERNET flags) inp  the network interface on which the packet was received
