PSGBK
Cross Reference (Contains links to field and bit definitions)
PSGBK Prolog
Name : HCPPSGBK
Description: POSIX supplementary GIDs Block
DSECT : PSGBK
Function : This DSECT is used to map the supplementary
GID list associated with a PXIBK
Located by : PXIPSGBK
Created by : Routines that create the associated PXIBK
Deleted by : Routines that create the associated PXIBK
Serialized : Share of any PXIBK lock in a PXIBK that
points to the PSGBK. See HCPPXIBK for additional
information.
Comments : PSGBKs are sometimes imbedded in a
PXIBK and are sometimes alone in their own free
storage block. A PSGBK can be pointed to by zero
or more PXIBKs.
