// These macros are used to provide function call trace information into
// the log. Each function (method) that wants to be traceable needs at a
// minimum to use the following three macros. The first macro needs to be
// put at the top of the source code file and defines to which module the
// code in that file belongs.
//
// #define WSB_TRACE_IS WSB_TRACE_BIT_PLATFORM
//
// The next two macros are used once per function. They are variable
// macros, which allows the writer of the function to list the values
// of the input and output parameters.
//
// HRESULT CWsbSample::Do(BOOL shouldWrite) {
// HRESULT hr = S_OK;

// WsbTraceIn("CWsbSample::Do", "shouldWrite = <%ls>", WsbBoolAsString(shouldWrite));

// ... some code ....

// return(hr);
// }
//
// Notice that some helper functions have been defined to help provide an
// a written description for the value of certain types. Additional helper
// helper functions should be created as needed.

Macro Name:
WsbTraceIn
Macro Description:
This macro is used to provide function call trace information into the log. It should be put at the start of the function.
Arguments:
methodName - The name of the function. argString - A printf type format string. Additional arguments can follow.

Macro Name:
WsbTraceOut
Macro Description:
This macro is used to provide function call trace information into the log. It should be put at the end of the function.
Arguments:
methodName - The name of the function. argString - A printf type format string. Additional arguments can follow.

/*++
Macro Name:
WsbLogEvent
Macro Description:
This routine writes a message into the system event log. The message is also written to the application trace file.
Arguments:
eventId - The message Id to log. dataSize - Size of arbitrary data. data - Arbitrary data buffer to display with the message. Inserts - Message inserts that are merged with the message description specified by eventId. The number of inserts must match the number specified by the message description. The last insert must be NULL to indicate the end of the insert list.
Notes:
It's a small optimization to check if logging is turned on, first. Determining if the message is actually logged still requires the first parameter. Unlike trace, log activity should be minimal and only when there are problems. The overhead of the calls seems reasonable.

Macro Name:
WsbLogEventV
Macro Description:
This macro is used to write a message into the system event log. The message is also written to the application trace file.
This macro is similar to WsbLogEvent, but takes a va_list as the fourth argument.
Arguments:
eventId - The message Id to log. dataSize - Size of arbitrary data. data - Arbitrary data buffer to display with the message. inserts - An array of message inserts that are merged with the message description specified by eventId. The number of inserts must match the number specified by the message description. The last insert must be NULL, to indicate the end of the insert list.

It's a small optimization to check if logging is turned on, first. Determining if the message is actually logged still requires the first parameter. Unlike trace, log activity should be minimal and only when there are problems. The overhead of the calls seems reasonable.

Macro Name:
WsbTraceAlways
Macro Description:
This macro is used to provide a printf style message into the trace file. The trace is printed if tracing has been started regardless of the WSB_TRACE_IS settings.
Arguments:
argString - A printf type format string. Additional arguments can follow.
