V(MQLONG)

 

Structure version number.

The value depends on the environment:

MQCXP_VERSION_1

Version-1 channel exit parameter structure.

MQCXP_VERSION_2

Version-2 channel exit parameter structure.

The field has this value in the following environments: HP OpenVMS, Compaq NonStop Kernel.

MQCXP_VERSION_3

Version-3 channel exit parameter structure.

The field has this value in the following environments: UNIX systems not listed elsewhere.

MQCXP_VERSION_4

Version-4 channel exit parameter structure.

MQCXP_VERSION_5

Version-5 channel exit parameter structure.

MQCXP_VERSION_6

Version-6 channel exit parameter structure.

The field has this value in the following environments: z/OS, AIX, HP-UX, Linux, i5/OS, Solaris, Windows.

Fields that exist only in the more-recent versions of the structure are identified as such in the descriptions of the fields. The following constant specifies the version number of the current version:

MQCXP_CURRENT_VERSION

Current version of channel exit parameter structure.

The value of this constant depends on the environment (see above).

When a new version of the MQCXP structure is introduced, the layout of the existing part is not changed. The exit should therefore check that the version number is equal to or greater than the lowest version which contains the fields that the exit needs to use.

This is an input field to the exit.
