StrucId (MQCHAR4) for MQDLH

This is the structure identifier of the dead letter header structure. It is always an input field. Its value is MQDLH_STRUC_ID.

The value must be:

MQDLH_STRUC_ID: Identifier for the dead letter header structure.
For the C programming language, the constant MQDLH_STRUC_ID_ARRAY is also defined. This has the same value as MQDLH_STRUC_ID, but is an array of characters instead of a string.
