StrucId (MQCHAR4)

The value must be:

    MQEPH_STRUC_ID
    Identifier for distribution header structure.

    For the C programming language, the constant MQEPH_STRUC_ID_ARRAY is also defined; this has the same value as MQDH_STRUC_ID, but is an array of characters instead of a string.

The initial value of this field is MQEPH_STRUC_ID.
