Introduction to the NOF API
NOF Indications
Chapter 1 85
The application does not need to register explicitly to receive this
indication; SNAplus2 returns it to any application that hasregistered for
any type of NOF indications on the appropriate target. The indication is
returned on the callback routine that the application supplied to the
REGISTER_INDICATION_SINK verb (or to the first
REGISTER_INDICATION_SINK verb, if the application has issued
more than one).
After the application receives an indication that the target has failed, all
subsequent verbs using the relevant target handle will be rejected,
except for DISCONNECT_NODE or CLOSE_FILE (to free the target
handle). In addition, any registrations for indications on this target
handle will be lost; in order to continue receiving indications when the
target becomes available, the application must connect again to the
target and register again for the required indications.
