Overview

Purpose: The MQCNO structure allows the application to specify options relating to the connection to the local queue manager. The structure is an input/output parameter on the MQCONNX call.

Version: The current version of MQCNO is CNVER4. Fields that exist only in the more-recent versions of the structure are identified as such in the descriptions that follow.

The COPY file provided contains the most recent version of MQCNO that is supported by the environment, but with the initial value of the CNVER field set to CNVER1. To use fields that are not present in the version-1 structure, the application must set the CNVER field to the version number of the version required.

Character set and encoding: Data in MQCNO must be in the character set and encoding of the local queue manager; these are given by the CodedCharSetId queue manager attribute and ENNAT, respectively.
