mqSetInteger64

The mqSetInteger64 call either modifies a 64-bit integer item that is already present in the bag, or deletes all existing occurrences of the specified selector and adds a new occurrence at the end of the bag. The data item is usually a user item, but specific system-data items can also be modified.


Syntax for mqSetInteger64

    mqSetInteger64 (Bag, Selector, ItemIndex, ItemValue, CompCode, Reason)


Parameters for mqSetInteger64

    Bag (MQHBAG) - input
    Handle of the bag to be set. This must be the handle of a bag created by the user, and not the handle of a system bag; MQRC_SYSTEM_BAG_NOT_ALTERABLE results if the handle you specify refers to a system bag.

    Selector (MQLONG) - input
    Selector of the item to be modified. If the selector is less than zero (that is, a system selector), the selector must be one that is supported by the MQAI; MQRC_SELECTOR_NOT_SUPPORTED results if it is not.

    If the selector is a supported system selector, but is one that is read-only, MQRC_SYSTEM_ITEM_NOT_ALTERABLE results.

    If the selector is an alterable system selector, but is always a single-instance selector and the application attempts to create a second instance in the bag, MQRC_MULTIPLE_INSTANCE_ERROR 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; MQRC_SELECTOR_OUT_OF_RANGE results if it is not. If MQCBO_CHECK_SELECTORS was not specified, the selector can be any value zero or greater.

    If MQIND_ALL is not specified for the ItemIndex parameter, the specified selector must already be present in the bag; MQRC_SELECTOR_NOT_PRESENT results if it is not.

    If MQIND_ALL is not specified for the ItemIndex parameter, the data type of the item must agree with the data type implied by the call; MQRC_SELECTOR_WRONG_TYPE results if it is not.

    ItemIndex (MQLONG) - input
    This value identifies the occurrence of the item with the specified selector that is to be modified. The value must be zero or greater, or one of the special values described in this topic; if it is none of these, MQRC_INDEX_ERROR results.

      Zero or greater
      The item with the specified index must already be present in the bag; MQRC_INDEX_NOT_PRESENT results if it is not. The index is counted relative to the items in the bag that have the specified selector. For example, if there are five items in the bag with the specified selector, the valid values for ItemIndex are 0 through 4.

      MQIND_NONE
      This specifies that there must be one occurrence only of the specified selector in the bag. If there is more than one occurrence, MQRC_SELECTOR_NOT_UNIQUE results.

      MQIND_ALL
      This specifies that all existing occurrences of the specified selector (if any) are to be deleted from the bag, and a new occurrence of the selector created at the end of the bag. Note: For system selectors, the order is not changed.

    ItemValue (MQINT64) - 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 indicating error and warning conditions can be returned from the mqSetInteger64 call:

      MQRC_HBAG_ERROR
      Bag handle not valid.

      MQRC_INDEX_ERROR
      Index not valid (index negative and not MQIND_NONE or MQIND_ALL).

      MQRC_INDEX_NOT_PRESENT
      No item with the specified index is present within the bag for the selector given.

      MQRC_MULTIPLE_INSTANCE_ERROR
      Multiple instances of system selector not valid.

      MQRC_SELECTOR_NOT_PRESENT
      No item with the specified selector is present within the bag.

      MQRC_SELECTOR_NOT_SUPPORTED
      Specified system selector not supported by the MQAI.

      MQRC_SELECTOR_NOT_UNIQUE
      MQIND_NONE specified when more than one occurrence of the specified selector is present in the bag.

      MQRC_SELECTOR_OUT_OF_RANGE
      Selector not in valid range for call.

      MQRC_SELECTOR_WRONG_TYPE
      Data item has wrong data type for call.

      MQRC_STORAGE_NOT_AVAILABLE
      Insufficient storage available.

      MQRC_SYSTEM_BAG_NOT_ALTERABLE
      System bag cannot be altered or deleted.

      MQRC_SYSTEM_ITEM_NOT_ALTERABLE
      System item is read only and cannot be altered.
