StartFcn

Callback function file to execute immediately before logging starts

Description

You configure StartFcn to execute a callback function file when all prelogging steps have been completed. You start logging by calling the start function. A start event occurs immediately before Logging is set to 'on'.

When a start event occurs, the function specified in StartFcn is passed two parameters: Obj and EventInfo. Obj is the object associated with the event, and EventInfo is an event structure containing the fields Type and Data. The Type field is set to 'Start'. The Data field contains a structure with the fields given below.
