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; for details, see ResponseRecOffset (MQLONG). 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 Version
is less than MQPMO_VERSION_2.
