Syntax

MQZ_DELETE_NAME (queue_manager, QName, ComponentData, Continuation,

CompCode, Reason)

Parameters

The MQZ_DELETE_NAME call has the following parameters.

queue_manager (MQCHAR48) - input

Queue manager name.
The name of the queue manager calling the component. This name is padded with blanks to the full length of the parameter; the name is not terminated by a null character.
The queue-manager name is passed to the component for information; the name service interface does not require the component to make use of it in any defined manner.

QName (MQCHAR48) - input

Queue name.
The name of the queue for which an entry is to be deleted. This name is padded with blanks to the full length of the parameter; the name is not terminated by a null character.

ComponentData (MQBYTE×ComponentDataLength) - input/output

Component data.
This data is kept by the queue manager on behalf of this particular component; any changes made to it by any of the functions provided by this component are preserved, and presented the next time one of this component's functions is called.
The length of this data area is passed by the queue manager in the ComponentDataLength parameter of the MQZ_INIT_NAME call.

Continuation (MQLONG) - output

Continuation indicator set by component.
For MQZ_DELETE_NAME , the queue manager does not attempt to invoke another component, whatever is returned in Continuation.
The following values can be specified:

MQZCI_DEFAULT

Continuation dependent on queue manager.

MQZCI_STOP

Do not continue with next component.

CompCode (MQLONG) - output

Completion code.
It is one of the following:

MQCC_OK

Successful completion.

MQCC_WARNING

Warning (partial completion).

MQCC_FAILED

Call failed.

Reason (MQLONG) - output

Reason code qualifying CompCode.
If CompCode is MQCC_OK:

MQRC_NONE

(0, X'000') No reason to report.

If CompCode is MQCC_WARNING:

MQRC_UNKNOWN_Q_NAME

(2288, X'8F0') Queue name not found.

Note:

It may not be possible to return this code if the underlying service simply responds with success for this case.

If CompCode is MQCC_FAILED:

MQRC_SERVICE_ERROR

(2289, X'8F1') Unexpected error occurred accessing service.

MQRC_SERVICE_NOT_AVAILABLE

(2285, X'8ED') Underlying service not available.

C invocation
MQZ_DELETE_NAME (queue_manager, QName, ComponentData, &Continuation,
                &CompCode, &Reason);
The parameters passed to the service are declared as follows:
MQCHAR48  queue_manager;          /* Queue manager name */
MQCHAR48  QName;             /* Queue name */
MQBYTE    ComponentData[n];  /* Component data */
MQLONG    Continuation;      /* Continuation indicator set by
                                component */
MQLONG    CompCode;          /* Completion code */
MQLONG    Reason;            /* Reason code qualifying CompCode */
