SysSockAccept (FUN) ¶ FUNCTION SysSockAccept : 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). InOut: Scope Name Type Comment Return SysSockAccept 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)
