ExitReason (MQLONG)

 

Reason for invoking exit.

This indicates the reason why the exit is being called. Possible values are:

MQXR_CONNECTION

Connection level processing.

The exit is invoked with this value twice for each connection:

• Before the MQCONN or MQCONNX call, so that the exit can perform connection-level initialization. The Function field has the value MQXF_INIT in this case.

  The MQXF_INIT exit function should be used for general initialization of the exit suite, and the MQXF_CONN or MQXF_CONNX exit functions should be used specifically for processing the MQCONN or MQCONNX calls.

• After the MQDISC call, so that the exit can perform connection-level termination. The Function field has the value MQXF_TERM in this case.

  The MQXF_TERM exit function should be used for general termination of the exit suite, and the MQXF_DISC exit function should be used specifically for processing the MQDISC call.

MQXR_BEFORE

Before API execution.

The Function field can have any of the MQXF_* values other than MQXF_INIT or MQXF_TERM.

For the MQGET call, this value occurs with the:

• MQXF_GET exit function before API execution

• MQXF_DATA_CONV_ON_GET exit function after API execution but before data conversion

MQXR_AFTER

After API execution.

The Function field can have any of the MQXF_* values other than MQXF_INIT, MQXF_TERM, or MQXF_DATA_CONV_ON_GET.

For the MQGET call, this value occurs with the:

• MQXF_GET exit function after both API execution and data conversion have been completed

This is an input field to the exit.
