NAME : HCPVUDBK
DESCRIPTION: Vestigial User Data Block
DSECT : VUDBK
FUNCTION : To contain Vestigial User Data (historical data for
resources owned by the user which have since been
destroyed).
LOCATED BY : VMDVUDBK Field of a base VMDBK
CREATED BY : VUDBKs are dynamically created by HCPASMDS or
HCPASNRS when destroying an address space.
DELETED BY : VUDBKs are deleted during log-off processing.
SERIALIZED : Access to this control block is obtained by acquiring
the owning user's VUDBK spin lock.
