raw_notifier_call_chain — Call functions in a raw notifier chain
int raw_notifier_call_chain ( | struct raw_notifier_head * | nh, |
| unsigned long | val, | |
| void * | v); |
nhPointer to head of the raw notifier chain
valValue passed unmodified to notifier function
vPointer passed unmodified to notifier function
Calls each function in a notifier chain in turn. The functions run in an undefined context. All locking must be provided by the caller.
If the return value of the notifier can be and'ed
with NOTIFY_STOP_MASK then raw_notifier_call_chain
will return immediately, with the return value of
the notifier function which halted execution.
Otherwise the return value is the return value
of the last notifier function called.
