6.25 CRCTX Routines Enhanced
6.25 CRCTX Routines Enhanced
V7.1-2
The system routines that you can use to manage the Counted Resource Context
Block (CRCTX) data structure have been improved. The following routines now
set and check the status (CRCTX$V_ITEM_VALID) of the CRCTX data structure:
• IOC$DEALLOC_CRCTX
• IOC$ALLOC_CNT_RES
• IOC$DEALLOC_CNT_RES
• IOC$LOAD_MAP
These routines have changed as follows:
If you call IOC$DEALLOC_CRCTX with a valid CRCTX status (CRCTX$V_
ITEM_VALID set to 1), the service returns a bad status. If the SYSBOOT
parameter SYSTEM_CHECK is set, the system will fail. This prevents users
from deallocating a CRCTX when they have valid resources that have not been
deallocated.
You must call IOC$ALLOC_CNT_RES with an invalid CRCTX status (CRCTX$V_
ITEM_VALID set to 0). If you call this routine with a valid status, OpenVMS
assumes that you will lose the resources mapped by this CRCTX. OpenVMS does
not allocate new resources and returns a bad status. If SYSTEM_CHECK is set,
the system will fail. IOC$ALLOC_CNT_RES sets the valid bit before it returns.
IOC$DEALLOC_CNT_RES must be called with a valid CRCTX (CRCTX$V_
ITEM_VALID set to 1). If you call IOC$DEALLOC_CNT_RES with an invalid
CRCTX, OpenVMS assumes that the other parameters are not valid, and returns
a bad status. If SYSTEM_CHECK is set, the system will fail. IOC$DEALLOC_
CNT_RES clears the valid bit before it returns.
IOC$LOAD_MAP must be called with a valid CRCTX. If it is called with
an invalid CRCTX (CRCTX$V_ITEM_VALID set to 0), it assumes that the
other parameters are also invalid, and returns a bad status. If the SYSBOOT
parameter SYSTEM_CHECK is set, the system will fail.
These improvements indicate to device support and privileged-code application
developers whether they need to deallocate scatter gather registers, which are
treated by OpenVMS as generic resources. If the CRCTX$V_ITEM_VALID bit is
set, IOC$DEALLOC_CNT_RES still needs to be called.
