Function Documentation

u16_t htons (  u16_t  val  )

Convert 16-bit quantity from host byte order to network byte order. This function is primarily used for converting variables from host byte order to network byte order. For converting constants to network byte order, use the HTONS() macro instead. Definition at line 1576 of file uip.c. Referenced by main(), uip_init(), and uip_tcpchksum().

static void uip_add_rcv_nxt (  u16_t  n  )  [static]

Definition at line 470 of file uip.c. References uip_conn::rcv_nxt, and uip_add32().

void uip_init (  void   )

uIP initialization function. This function should be called at boot up to initilize the uIP TCP/IP stack. Definition at line 178 of file uip.c. References CLOSED, htons(), HTONS, uip_conn::initialmss, uip_conn::len, uip_conn::lport, uip_conn::mss, uip_conn::nrtx, uip_conn::ripaddr, uip_conn::rport, uip_conn::rto, uip_conn::sa, uip_conn::snd_nxt, uip_conn::sv, SYN_SENT, uip_conn::tcpstateflags, TIME_WAIT, uip_conn::timer, UIP_ACTIVE_OPEN, uip_connect(), UIP_FIXEDADDR, UIP_LISTENPORTS, UIP_RTO, UIP_TCP_MSS, and uip_udp_new(). Referenced by main().

void uip_listen (  u16_t  port  )

Start listening to the specified port. Note: Since this function expects the port number in network byte order, a conversion using HTONS() or htons() is necessary. uip_listen(HTONS(80)); Parameters: port  A 16-bit port number in network byte order. Definition at line 326 of file uip.c. Referenced by example5_init().

void uip_process (  u8_t  flag  )

Definition at line 480 of file uip.c. References BUF, CLOSED, CLOSING, FIN_WAIT_1, FIN_WAIT_2, LAST_ACK, SYN_RCVD, SYN_SENT, uip_stats::tcp, TCP_ACK, TCP_RST, uip_conn::tcpstateflags, TIME_WAIT, uip_conn::timer, TS_MASK, UIP_ACTIVE_OPEN, UIP_APPCALL, UIP_LLH_LEN, UIP_MAXRTX, UIP_MAXSYNRTX, uip_outstanding, UIP_REASSEMBLY, UIP_REXMIT, UIP_RTO, UIP_STAT, UIP_TIME_WAIT_TIMEOUT, UIP_TIMEDOUT, and UIP_TIMER.

void uip_unlisten (  u16_t  port  )

Stop listening to the specified port. Note: Since this function expects the port number in network byte order, a conversion using HTONS() or htons() is necessary. uip_unlisten(HTONS(80)); Parameters: port  A 16-bit port number in network byte order. Definition at line 315 of file uip.c.

volatile u8_t* uip_appdata

Pointer to the application data in the packet buffer. This pointer points to the application data when the application is called. If the application wishes to send data, the application may use this space to write the data into before calling uip_send(). Definition at line 92 of file uip.c. Referenced by uip_tcpchksum().

u8_t uip_buf[UIP_BUFSIZE+2]

The uIP packet buffer. The uip_buf array is used to hold incoming and outgoing packets. The device driver should place incoming data into this buffer. When sending data, the device driver should read the link level headers and the TCP/IP headers from this buffer. The size of the link level headers is configured by the UIP_LLH_LEN define. Note: The application data need not be placed in this buffer, so the device driver must read it from the place pointed to by the uip_appdata pointer as illustrated by the following example: void devicedriver_send(void) { hwsend(&uip_buf[0], UIP_LLH_LEN); hwsend(&uip_buf[UIP_LLH_LEN], 40); hwsend(uip_appdata, uip_len - 40 - UIP_LLH_LEN); } Definition at line 90 of file uip.c.
