SOCK_RECVMSG_MSG (STRUCT) ¶ TYPE SOCK_RECVMSG_MSG : STRUCT The SysSockRecvMsg() call uses a SOCK_RECVMSG_MSG structure to minimize the number of directly supplied arguments. InOut: Name Type Comment pBuffer POINTER TO BYTE OUT: Points to a buffer where the message should be stored. length __XWORD IN: Specifies the length in bytes of the buffer pointed to by the pBuffer argument. address SOCKADDRESS OUT: Sending address (AKA source address). msgFlags DWORD OUT: A 32-bit value to store the flags of the incoming message. msgFlagsSupported DWORD OUT: A 32-bit value to store which message flags for the pMsgFlags argument are supported by the implementation of the runtime system. See category “Message flags”.

InOut: Name Type Comment szHostname REFERENCE TO STRING Official name of host (network name) pAliasList POINTER TO POINTER TO STRING Pointer to list of aliases iHostAddrType INT Address type of host iLengthAddr INT Size of host address pAddrList POINTER TO POINTER TO STRING Pointer to address list

UDINT_IN_BYTES (STRUCT) ¶ TYPE UDINT_IN_BYTES : STRUCT This structure contains the IP address in dotted decimal notation. Example: The IP address 10000010 01011110 01111010 11000011 will be translated to 130.094.122.195 in dotted decimal notation. Each of the 4 number blocks builds an entry of the structure UDINT_IN_BYTES. InOut: Name Type Comment s_b1 BYTE First decimal block, in the example 130 s_b2 BYTE Second decimal block, in the example 094 s_b3 BYTE Third decimal block, in the example 122 s_b4 BYTE Fourth decimal block, in the example 195

UDINT_IN_WORDS (STRUCT) ¶ TYPE UDINT_IN_WORDS : STRUCT This structure contains the IP address for a word-by-word access. Example: The IP address 10000010 01011110 01111010 11000011 for word-by-word access is 33374.31427. Each of the both number blocks builds an entry of the structure UDINT_IN_WORDS. InOut: Name Type Comment s_w1 WORD First decimal block, in the example 33374 s_w2 WORD Second decimal block, in the example 31427
