As udp sockets aren't connection oriented those errors will be * anounced asynchronously on the next NutUdpSend or NutUdpReceive * * Include "include/errno.h" instead of "include/net/errno.h" * * Revision 1.11 2008/08/20 06:56:59 haraldkipp * Implemented IP demultiplexer. * * Revision 1.10 2008/08/11 07:00:27 haraldkipp * BSD types replaced by stdint types (feature request #1282721). * * Revision 1.9 2008/04/18 13:32:00 haraldkipp * Changed size parameter from u_short to int, which is easier to handle * for 32-bit targets. You need to recompile your ARM code. No impact on * AVR expected * I changed u_int to int at some places to avoid some warnings during * compilation of Nut/Net. * libs. * * Revision 1.8 2005/07/26 15:49:59 haraldkipp * Cygwin support added. * * Revision 1.7 2005/04/08 10:01:21 freckle * removed #defines from unix emulation as provided by system headers * * Revision 1.6 2005/04/04 19:33:54 freckle * added creation of include/netdb_orig.h, include/sys/socket_orig.h and * include/netinet/in_orig.h to allow unix emulation to use tcp/ip sockets * * Revision 1.5 2004/07/30 19:54:46 drsung * Some code of TCP stack redesigned. Round trip time calculation is now * supported. Fixed several bugs in TCP state machine. Now TCP connections * should be more reliable under heavy traffic or poor physical connections. * * Revision 1.4 2004/03/16 16:48:44 haraldkipp * Added Jan Dubiec's H8/300 port. * * Revision 1.3 2004/02/02 19:03:09 drsung * Some more ICMP support added. * * Revision 1.2 2003/11/24 21:00:21 drsung * Packet queue added for UDP sockets. * * Revision 1.1.1.1 2003/05/09 14:41:21 haraldkipp * Initial using 3.2.1 * * Revision 1.7 2003/02/04 18:00:53 harald * Version 3 released * * Revision 1.6 2002/09/15 16:46:57 harald * Error prototype added * * Revision 1.5 2002/06/26 17:29:29 harald * First pre-release with 2.4 stack * */ #include #if defined(__linux__) || defined(__APPLE__) || defined(__CYGWIN__) /* use native version on unix emulation */ #include #else /* embedded systems */ #include /*! * \addtogroup xgSocket */ /* * Types */ #define SOCK_STREAM 1 /*!< \brief Stream socket */ #define SOCK_DGRAM 2 /*!< \brief Datagram socket */ #define SOCK_RAW 3 /*!< \brief Raw-protocol interface */ /* * Option flags per-socket. */ #define SO_DEBUG 0x0001 /*!< \brief Turn on debugging info recording */ #define SO_ACCEPTCONN 0x0002 /*!< \brief Socket has had listen() */ #define SO_REUSEADDR 0x0004 /*!< \brief Allow local address reuse */ #define SO_KEEPALIVE 0x0008 /*!< \brief Keep connections alive */ #define SO_DONTROUTE 0x0010 /*!< \brief Just use interface addresses */ #define SO_BROADCAST 0x0020 /*!< \brief Permit sending of broadcast msgs */ #define SO_USELOOPBACK 0x0040 /*!< \brief Bypass hardware when possible */ #define SO_LINGER 0x0080 /*!< \brief Linger on close if data present */ #define SO_OOBINLINE 0x0100 /*!< \brief Leave received OOB data in line */ #define SO_REUSEPORT 0x0200 /*!< \brief Allow local address & port reuse */ /* * Additional options, not kept in so_options. */ #define SO_SNDBUF 0x1001 /*!< \brief Send buffer size */ #define SO_RCVBUF 0x1002 /*!< \brief Receive buffer size */ #define SO_SNDLOWAT 0x1003 /*!< \brief Send low-water mark */ #define SO_RCVLOWAT 0x1004 /*!< \brief Receive low-water mark */ #define SO_SNDTIMEO 0x1005 /*!< \brief Send timeout */ #define SO_RCVTIMEO 0x1006 /*!< \brief Receive timeout */ #define SO_ERROR 0x1007 /*!< \brief Get error status and clear */ #define SO_TYPE 0x1008 /*!< \brief Get socket type */ /* * Address families. */ #define AF_INET 2 /*!< \brief internetwork: UDP, TCP, etc. */ #endif /* unix / embedded */ /* assure _SYS_SOCKET_H_ is set */ #undef _SYS_SOCKET_H_ #define _SYS_SOCKET_H_ #include #include /*! * \file sys/socket.h * \brief UDP and TCP socket interface definitions. */ extern TCPSOCKET *NutTcpCreateSocket(void); extern int NutTcpSetSockOpt(TCPSOCKET *sock, int optname, const void *optval, int optlen); extern int NutTcpGetSockOpt(TCPSOCKET *sock, int optname, void *optval, int optlen); extern int NutTcpConnect(TCPSOCKET *sock, uint32_t addr, uint16_t port); extern int NutTcpAccept(TCPSOCKET *sock, uint16_t port); extern int NutTcpInput(NUTDEVICE * dev, NETBUF *nb); extern int NutTcpSend(TCPSOCKET *sock, const void *data, int len); #ifdef __HARVARD_ARCH__ extern int NutTcpSend_P(TCPSOCKET *sock, PGM_P data, int len); #endif extern int NutTcpCloseSocket(TCPSOCKET *sock); extern void NutTcpDestroySocket(TCPSOCKET *sock); extern int NutTcpReceive(TCPSOCKET *sock, void *data, int size); extern TCPSOCKET *NutTcpFindSocket(uint16_t lport, uint16_t rport, uint32_t raddr); extern int NutTcpError(TCPSOCKET *sock); extern int NutTcpAbortSocket(TCPSOCKET *sock, uint16_t last_error); extern void NutTcpDiscardBuffers(TCPSOCKET * sock); extern int NutTcpDeviceRead(TCPSOCKET *sock, void *buffer, int size); extern int NutTcpDeviceWrite(TCPSOCKET *sock, const void *buffer, int size); #ifdef __HARVARD_ARCH__ extern int NutTcpDeviceWrite_P(TCPSOCKET *sock, PGM_P buffer, int size); #endif extern int NutTcpDeviceIOCtl(TCPSOCKET *sock, int cmd, void *param); #ifndef CRT_DISABLE_SELECT_POLL extern int NutTcpDeviceSelect (TCPSOCKET * sock, int flags, HANDLE *wq, select_cmd_t cmd); #else #define NutTcpDeviceSelect NULL #endif extern int NutTcpDeviceClose(TCPSOCKET *sock); extern UDPSOCKET *NutUdpCreateSocket(uint16_t port); extern int NutUdpSendTo(UDPSOCKET *sock, uint32_t addr, uint16_t port, void *data, int len); extern int NutUdpReceiveFrom(UDPSOCKET *sock, uint32_t *addr, uint16_t *port, void *data, int size, uint32_t timeout); extern int NutUdpDestroySocket(UDPSOCKET *sock); extern UDPSOCKET *NutUdpFindSocket(uint16_t port); extern int NutUdpSetSockOpt(UDPSOCKET *sock, int optname, const void *optval, int optlen); extern int NutUdpGetSockOpt(UDPSOCKET *sock, int optname, void *optval, int optlen); #ifndef NUT_UDP_ICMP_EXCLUDE extern int NutUdpSetSocketError(UDPSOCKET * sock, uint32_t remote_addr, uint16_t remote_port, uint16_t error); extern int NutUdpError(UDPSOCKET * sock, uint32_t * addr, uint16_t * port); #endif #endif
