Detailed Description

Notification

A notification structure allows the user to define a notification event and a destination queue with an optional event group. EM will notify the user by sending the event into the given queue.

The egroup-field defines an optional event group for this notification. The used event group has to exist and be initialized. Use value EM_EVENT_GROUP_UNDEF for normal operation (API 1.0 functionality), i.e. notification is not sent to a group. egroup should not be the originating group, i.e. should not be sent back to the group.

Attention: API 1.0 code using notifications may need to be modified as the new field need to be initialized. Value EM_EVENT_GROUP_UNDEF is the correct value to use for non-group notification but value 0 is an alias, e.g. it is safe to initialize the structure with memset(0,..).
