SSCBK Prolog
NAME : HCPSSCBK
DESCRIPTION: SYSTEM SERVICE CONTROL BLOCK
DSECT : SSCBK
FUNCTION : THIS CONTROL BLOCK PROVIDES AN ANCHOR AND A
REPOSITORY FOR INFORMATION REQUIRED BY THE TSAF-RELATED
SYSTEM SERVICES, *IDENT AND *CRM.
LOCATED BY : SYSSSCBK FIELD OF SYSCM
CREATED BY : HCPIUAIN
DELETED BY : NONE
SERIALIZED : THERE IS NO GENERAL LOCKING STRUCTURE OVER THIS
BLOCK, BUT THERE ARE SEVERAL FIELDS WHICH ARE MODIFIED
VIA COMPARE AND SWAP IN ORDER TO ENSURE THEIR INTEGRITY:
SSCHIPTH AND SSCTGCNT.
ALSO, THE HASH TABLE PLISTS CONTAINED HEREIN ARE LOCKED
BY HCPGAL. SEE HCPGAL FOR MORE INFORMATION.
NOTES : THIS COPY FILE REQUIRES THE FOLLOWING IN ORDER
TO GENERATE PROPERLY:
- HCPGALPL
