UserData (MQCHAR128)

This is a character string that contains user information relevant to the application to be started, and is used by the trigger-monitor application that receives the trigger message. The queue manager initializes this field with the value of the UserData attribute of the process object identified by the ProcessName field; see Attributes for process definitions for details of this attribute. The content of this data is of no significance to the queue manager.

For Microsoft Windows, the character string must not contain double quotation marks if the process definition is going to be passed to runmqtrm.

The length of this field is given by MQ_PROCESS_USER_DATA_LENGTH. The initial value of this field is the null string in C, and 128 blank characters in other programming languages.
