Overview

Purpose: The MQWIH structure describes the information that must be present at the start of a message that is to be handled by the z/OS workload manager.

Format name: FMWIH.

Character set and encoding: The fields in the MQWIH structure are in the character set and encoding given by the MDCSI and MDENC fields in the header structure that precedes MQWIH, or by those fields in the MQMD structure if the MQWIH is at the start of the application message data.

The character set must be one that has single-byte characters for the characters that are valid in queue names.

Usage: If a message is to be processed by the z/OS workload manager, the message must begin with an MQWIH structure.
