StrucLength (MQLONG)

 

Length of MQACH structure.

This is the length of the MQACH structure itself; this length excludes the exit-defined data that follows the MQACH structure (see the ChainAreaLength field).

• The exit function that creates the MQACH structure must set this field to the length of the MQACH.

• An exit function that wants to access the exit-defined data should use StrucLength as the offset of the exit-defined data from the start of the MQACH structure.

The following value is defined:

MQACH_LENGTH_1

Length of version-1 MQACH structure.

The following constant specifies the length of the current version:

MQACH_CURRENT_LENGTH

Length of current version of exit chain area header.

The initial value of this field is MQACH_CURRENT_LENGTH.
