mqAddInteger

The mqAddInteger call adds an integer item identified by a user selector to the end of a specified bag.

Syntax for mqAddInteger

mqAddInteger (Bag, Selector, ItemValue, CompCode, Reason)

Parameters for mqAddInteger

Bag (MQHBAG) - input

Handle of the bag to be modified.

This must be the handle of a bag created by the user, not the handle of a system bag. MQRC_SYSTEM_BAG_NOT_ALTERABLE results if the value you specify identifies a system bag.

Selector (MQLONG)

Selector identifying the item to be added to the bag.

If the selector is less than zero (that is, a system selector), MQRC_SELECTOR_OUT_OF_RANGE results.

If the selector is zero or greater (that is, a user selector) and the bag was created with the MQCBO_CHECK_SELECTORS option or as an administration bag (MQCBO_ADMIN_BAG), the selector must be in the range MQIA_FIRST through MQIA_LAST; if not, again MQRC_SELECTOR_OUT_OF_RANGE results.

If MQCBO_CHECK_SELECTORS was not specified, the selector can be any value of zero or greater.

If the call is creating a second or later occurrence of a selector that is already in the bag, the data type of this occurrence must be the same as the data type of the first occurrence; MQRC_INCONSISTENT_ITEM_TYPE results if it is not.

ItemValue (MQLONG) - input

The integer value to be placed in the bag.

CompCode (MQLONG) - output

Completion code.

Reason (MQLONG) - output

Reason code qualifying CompCode. The following reason codes indicate error conditions that can be returned from the mqAddInteger call:

MQRC_HBAG_ERROR

Bag handle not valid.

MQRC_INCONSISTENT_ITEM_TYPE

Data type of this occurrence of selector differs from data type of first occurrence.

MQRC_SELECTOR_OUT_OF_RANGE

Selector not within valid range for call.

MQRC_STORAGE_NOT_AVAILABLE

Insufficient storage available.

MQRC_SYSTEM_BAG_NOT_ALTERABLE

System bag cannot be altered or deleted.

Usage notes for mqAddInteger

1. If a data item with the specified selector is already present in the bag, an additional instance of that selector is added to the end of the bag. The new instance is not necessarily next to the existing instance.
2. This call cannot be used to add a system selector to a bag.
