OPTION (STRUCT)¶

TYPE OPTION : STRUCT

Option can be used to set socket options, e.g. unsing the IOptionProvider

Example for keep alive could be:

VAR
     _Keepalive : RTS_SOCKET_SO_VALUE_TCP_KEEPALIVE := (
         bOn := 1,
         probes := 5,
         timeout := 100,
         interval := 100
     );
     myOptionKeepalive : NBS.OPTION := (
         diLevel := SOCKET_SOL,
         diOption := SOCKET_SO_KEEPALIVE,
         pdiOptionValue := ADR(_Keepalive),
         udiOptionLen := SIZEOF(_Keepalive)
     );
END_VAR

InOut:

Name	Type
`diLevel`	`DINT`
`diOption`	`DINT`
`pdiOptionValue`	POINTER TO DINT
`udiOptionLen`	`UDINT`
