ResponseRecPtr (MQPTR)

This is the address of the first MQRR response record. ResponseRecPtr is used only when the message is being put to a distribution list. The field is ignored if RecsPresent is zero.

Use either ResponseRecPtr or ResponseRecOffset to specify the response records, but not both; see the description of the ResponseRecOffset field above for details. If you do not use ResponseRecPtr set it to the null pointer or null bytes.

For the MQPUT1 call, this field must be the null pointer or null bytes. This is because the response information (if requested) is returned in the response records specified by the object descriptor MQOD.

This is an input field. The initial value of this field is the null pointer in those programming languages that support pointers, and an all-null byte string otherwise. This field is ignored if Vis less than MQPMO_VERSION_2.

Note:
On platforms where the programming language does not support the pointer data type, this field is declared as a byte string of the appropriate length, with the initial value being the all-null byte string.
