The port driver calls the Storport virtual miniport's HwStorInitializeTracing at PASSIVE_LEVEL.
To define an HwStorInitializeTracing callback function, you must first provide a function declaration that identifies the type of callback function you’re defining. Windows provides a set of callback function types for drivers. Declaring a function using the callback function types helps Code Analysis for Drivers, Static Driver Verifier (SDV), and other verification tools find errors, and it’s a requirement for writing drivers for the Windows operating system.
For example, to define a HwStorInitializeTracing callback routine that is named MyHwInitializeTracing, use the HW_INITIALIZE_TRACING type as shown in this code example:
The HW_INITIALIZE_TRACING function type is defined in the Storport.h header file. To more accurately identify errors when you run the code analysis tools, be sure to add the Use_decl_annotations annotation to your function definition. The Use_decl_annotations annotation ensures that the annotations that are applied to the HW_INITIALIZE_TRACING function type in the header file are used. For more information about the requirements for function declarations, see Declaring Functions Using Function Role Types for Storport Drivers. For information about Use_decl_annotations, see Annotating Function Behavior.
