USXBK Prolog
NAME : HCPUSXBK
DESCRIPTION: User Security Extension Block
DSECT : USXBK
FUNCTION : The USXBK contains pointers to the block(s)
of storage containing the altered security flags for
a particular user, or zeroes, if no block exists for
that set of entities.
LOCATED BY : VMDACIMP field of the VMDBK
CREATED BY : HCPDA0
DELETED BY : HCPDA0, HCPUSO, HCPLOG
SERIALIZED : The SYSCM lock, SYSUSXLK
Notes : This control block is bilingual. The fields within it can
be referenced in either ASSEMBLER or PLAS modules.
The block of storage pointed to by each pointer field
in the USXBK consists of as many bytes as there are entries
in its corresponding data area. For example, USXCP
would point to a block of storage containing as many
bytes as there are command table entries. These
bytes have a one to one correspondence with the entries
in the command table. IE the 5th byte contains the
extended security flags relative to the 5th command
defined within the command table.
