NewMsgHandle (MQHMSG)

This is an optional handle to the message being put subject to the value of the Action field. It defines the properties of the message and overrides the values of the OriginalMsgHandle, if specified.

On return from the MQPUT or MQPUT1 call, the contents of the handle reflect the message that was actually put.

This is an input field. The initial value of this field is MQHM_NONE. This field is ignored if Version is less than MQPMO_VERSION_3.
