Purpose

OS/2 provides a mechanism by which developers may dynamically apply tracepoints in their module at run time. This method eliminates all overhead of tracing when tracing is disabled. It also allows the developer to add tracepoints without modifying source code. This reduces the possibility that adding a tracepoint will induce errors into one's code. OS/2 needs a binary file, for each module being dynamically traced, which defines the tracepoints for the module.

Description

The Trace Customizer (TRCUST) converts tracepoint definitions from a trace source file (TSF) into dynamic tracepoints for the trace definition file (TDF), and into formatting rules in the trace format file (TFF). For more information see Dynamic Trace Customizer (TRCUST).
