Removes a notification routine for receiving broadcasts of changes to configurable system variables.
#include <sys/types.h> #include <sys/errno.h> #include <sys/sysconfig.h> void cfgndel ( cbp) struct cfgncb *cbp;
| Item | Description |
|---|---|
| cbp | Points
to a cfgncb configuration notification control
block. On a platform that supports storage keys, the passed in cbp parameter must only be in the KKEY_PUBLIC domain. |
The cfgndel kernel service removes a previously registered cfgncb configuration notification control block from the list of cfgncb structures maintained by the kernel. This service thus allows kernel routines and extensions to remove their notification routines from the list of those called when a configurable system variable has been changed.
The address of the cfgncb structure passed to the cfgndel kernel service must be the same address used to call the cfgnadd service when the structure was originally added to the list. The /usr/include/sys/sysconfig.h file contains a definition of the cfgncb structure.
The cfgndel kernel service can be called from the process environment only.
The cfgndel service has no return values.
