How to Insert Trace Points in a Component

Trace points can be added manually to trace specific-required events in the source code or component at build time.

To instrument a component, the Instrumentor can use the methods given in the epoc32/include/e32utrace.h file. The UTrace API provides some basic information for each trace, but the developer has to define the payload of the trace. It is recommended the Instrumentor is consistent whilst adding traces in order to help the Trace Collector parse the trace output once it is on the host. For example, being consistent while formatting an Object ID or Object Name.
