iosGetObjectAccess - get access to object and start notification process
iosGetObjectAccess ?-event eventlist? pv-name
This command deliveres a identifier, with which you can access objects in the
point database.
With the option -event you can specify, how your script will be
notified, whenever changes in the value/structure/existance of the object occur.
Eventlist defaults to no notifications at all.
For the valid options read about event processing.
Example:
iosGetObjectAccess my_int
iosGetObjectAccess -event {notify change} my_float
iosGetObjectAccess -event change my_string
The result is the object ID of the process variable. If an error occured while
accessing the object, the object ID will be 0. The ID has to be kept, since all access and notification to/from the object is handled with this (unique) id.
