VCB Structure

typedef struct delete_downstream_lu
{
        unsigned short  opcode;           /* verb operation code        */
        unsigned char   attributes;       /* verb attributes            */
        unsigned char   format;           /* format                     */
        unsigned short  primary_rc;       /* primary return code        */
        unsigned long   secondary_rc;     /* secondary return code      */
        unsigned char   dslu_name[8];     /* Downstream LU name         */
} DELETE_DOWNSTREAM_LU;

Supplied Parameters

The application supplies the following parameters:
opcode
AP_DELETE_DOWNSTREAM_LU
attributes
The attributes of the verb. This field is a bit field. The first bit contains the visibility of the resource to be defined and corresponds to one of the following:

AP_EXTERNALLY_VISIBLE
AP_INTERNALLY_VISIBLE

The other values that can be bit-wise ORed into this field are as follows:
AP_DELAY_IF_REQUIRED
This specifies that the downstream LU specified by dslu_name is currently active, this verb should be queued inside the Program until the LU becomes inactive. In this case, the verb is processed to completion when the LU becomes inactive.
format
Identifies the format of the VCB. Set this field to zero to specify the version of the VCB listed above.
dslu_name
Name of the downstream LU that is being deleted. This is an 8-byte alphanumeric type-A EBCDIC string (starting with a letter), padded to the right with EBCDIC spaces.
