14.7.2 Profile with automatic recording
The following example builds upon the aforementioned by adding two points:
For one thing, recording takes place automatically. For that to happen, a
sampling in 10ms intervals is set with DataRecApiSetRecContext, while fur-
thermore a start delay of 2 seconds and a recording time of 5 seconds is set
with DataRecApiSetRecCount. For another, a callback from the recording
into the application is configured for the purpose of minimum-maximum de-
termination.
