Close(PLU) Response

  • Artigo

The Close(PLU) Response message flows from the node to the application and from the application to the node. It is used with a primary logical unit (PLU) connection.

Syntax

  
struct Close(PLU) Response {  
    PTRBFHDR  nxtqptr;  
    PTRBFELT  hdreptr;  
    CHAR      numelts;  
    CHAR      msgtype;  
    CHAR      srcl;  
    CHAR      srcp;  
    INTEGER   srci;  
    CHAR      destl;  
    CHAR      destp;  
    INTEGER   desti;  
    CHAR      clhdr.closqual;  
    CHAR      clhdr.clstype;  
};

Members

nxtqptr
Pointer to next buffer header.

hdreptr
Pointer to buffer element (NIL).

numelts
Number of buffer elements (0x00).

msgtype
Message type CLOSEMSG (0x02).

srcl
Source locality.

srcp
Source partner.

srci
Source index.

destl
Destination locality.

destp
Destination partner.

desti
Destination index.

clhdr.closqual
Close qualifier RSPOK (0x02).

clhdr.clstype
Close subtype LUSEC (0x02).

Remarks

  • The Close(PLU) Response message consists of a buffer header only. There is no buffer element.

  • The Close(PLU) protocol is unconditional. It is not possible for the recipient of a Close(PLU) Request (either the local node or an application) to keep the PLU connection open. The only valid response is Close(PLU) Response with the close qualifier as RSPOK.
