+    * Creates a trace context for traceable function. This variant is used with plain functions and static methods.
+    * Parameter @a _fn defines the name of the function (method) to trace. @_id defines the group where this trace entry belongs.
+    * For full list of available trace contexts, see file a3f_trace_ctxt.h. Parameter @a _vis defines the visibility this context is having.
+    * Methods / functions with IMPORT_C / EXPORT_C definitions are marked as DPAPI, others have signature DPLOCAL.
+    * Parameter @a _thdId is a name for a variable to create when thread id is queried from kernel. Later in the code you can use this
+    * variable e.g. to instantiate other trace enabled classes.\n\n
+    * Usage example:
+    * @code
+    * DP_CONTEXT(FooBar, CtxTest, DPAPI, thdId);
+    * ...
+    * TRACE_FAST_CREATE(thdId);
