Availability: AIX, HP-UX, i5/OS, Solaris, Linux, Windows, plus WebSphere MQ clients connected to these systems.
Purpose: Use the MQPMR structure to specify various message properties for a single destination when putting a message to a distribution list. MQPMR is an input/output structure for the MQPUT and MQPUT1 calls.
Character set and encoding: Data in MQPMR must be in the character set and encoding of the local queue manager; these are given by the CodedCharSetId queue-manager attribute and MQENC_NATIVE, respectively. However, if the application is running as an MQ client, the structure must be in the character set and encoding of the client.
Usage: By providing an array of these structures on the MQPUT or MQPUT1 call, you can specify different values for each destination queue in a distribution list. Some of the fields are input only, others are input/output.
Fields that are absent occupy no space in the record.
Because MQPMR does not have a fixed layout, no definition of it is provided in the header, COPY, and INCLUDE files for the supported programming languages. The application programmer must create a declaration containing the fields that are required by the application, and set the flags in PutMsgRecFields to indicate the fields that are present.
