SysSock2Accept (FUN) ¶ FUNCTION SysSock2Accept : RTS_IEC_HANDLE Accept the next incoming TCP connection. This functions calls the function accept of the operating system, which can accept a request to connect to a socket. A new descriptor (handle) for the socket is returned. The original socket is reset to the “listening” state (see SysSockListen). Note For TLS Sockets the blocking mode will be set to nonblocking for the new client sockets. If a blocking behavior is needed use SysSock2Ioctl to set the socket to blocking mode. This reflects the behavior of SysSock2Create for TLS sockets. InOut: Scope Name Type Comment Return SysSock2Accept RTS_IEC_HANDLE Handle to the new accepted socket or RTS_INVALID_HANDLE if failed. Input hSocket RTS_IEC_HANDLE Handle to the socket pSockAddr POINTER TO SOCKADDRESS Socket address of the client, who is connected pdiSockAddrSize POINTER TO DINT Pointer to size of socket address structure pResult POINTER TO RTS_IEC_RESULT Pointer to runtime system error code (see CmpErrors.library)

SysSock2Bind (FUN) ¶ FUNCTION SysSock2Bind : RTS_IEC_RESULT Bind a socket to a socket address and port number. This functions calls the function bind of the operating system, which will assign a local address to a socket that has already been allocated to an address by SysSock2Create , but not yet fixed uniquely. This is usually done previous to a call to functions like SysSock2Listen or SysSock2Accept . InOut: Scope Name Type Comment Return SysSock2Bind RTS_IEC_RESULT Runtime system error code (see CmpErrors.library). Input hSocket RTS_IEC_HANDLE Handle to the socket pSockAddr POINTER TO SOCKADDRESS Spcket address diSockAddrSize DINT Size of the socket address structure

SysSock2Close (FUN) ¶ FUNCTION SysSock2Close : RTS_IEC_RESULT Close a socket. InOut: Scope Name Type Comment Return SysSock2Close RTS_IEC_RESULT Runtime system error code (see CmpErrors.library). Input hSocket RTS_IEC_HANDLE Handle to the socket
