NSClientClose (FUN) ¶ FUNCTION NSClientClose : RTS_IEC_RESULT Close an instance of the nameservice client. Callbacks that arrive after the client has been closed will no longer be forwarded. Returns the result of the operation, ERR_OK if a valid instance has been given in. InOut: Scope Name Type Comment Return NSClientClose RTS_IEC_RESULT Input hNSClient RTS_IEC_HANDLE Handle of the nameservice client that is to be closed

NSClientOpen (FUN) ¶ FUNCTION NSClientOpen : RTS_IEC_HANDLE Opens an instance of the nameservice client. Returns the handle to the created name service client. InOut: Scope Name Type Comment Return NSClientOpen RTS_IEC_HANDLE Input pResult POINTER TO RTS_IEC_RESULT Will optionally receive an error code if the creation of a nameservice client has failed. Otherwise ERR_OK will be returned.

NSClientResolveAll (FUN) ¶ FUNCTION NSClientResolveAll : RTS_IEC_RESULT Initiates the resolving of all available runtimes. Returns the result of the operation. InOut: Scope Name Type Comment Return NSClientResolveAll RTS_IEC_RESULT Input hNSClient RTS_IEC_HANDLE The instance of a nameservice client that shall to do the nameresolving udiReqId __UXINT Identifies the request. pfnResponseCallback POINTER TO BYTE Prototype see NSClientResponseCallback. This callback will be triggered for each available node
