StrucId (MQCHAR4)

Callback descriptor structure - StrucId field

This is the structure identifier; the value must be:

MQCBD_STRUC_ID: Identifier for callback descriptor structure.
For the C programming language, the constant MQCBD_STRUC_ID_ARRAY is also defined; this has the same value as MQCBD_STRUC_ID, but is an array of characters instead of a string.

This is always an input field. The initial value of this field is MQCBD_STRUC_ID.
