* Procedure enter/exit tracking.
|
|
*
|
|
* Start a procedure with
|
|
*
|
|
* EnterProc(ProcedureName, (_ "format", arg, arg, arg, ...));
|
|
* EnterProcS(ProcedureName, (_ "format", arg, arg, arg, ...));

|
* EnterProcI(ProcedureName, (_ "format", arg, arg, arg, ...));
|
|
* EnterProcR(ProcedureName, (_ "format", arg, arg, arg, ...));
|
|
*
|
|
* The format string is documented in EmitPal.
|
|
*
|
|
* Suffixing an "S" indicates that the macro should not generate
|
|
* a procedure name because there is a formal parameter with the
|
|
* name s_szProc. This is a hack.
|
|
*
|
|
* Suffixing an "R" indicates that the macro should generate a
|
|
* procedure name in RDEBUG.
|
|
*
|
|
* Suffixing an "I" indicates that the macro should emit a dummy
|
|
* procedure name in RDEBUG because the interface is internal.
|
|
*
|
|
* No suffix means that the macro should be active only in the
|
|
* DEBUG build and should vanish in RDEBUG (and RETAIL).
|
|
*
|
|
* End a procedure with one of the following:
|
|
*
|
|
* ExitProc();
|
|
*
|
|
* Procedure returns no value.
|
|
*
|
|
* ExitProcX();
|
|
*
|
|
* Procedure returns an arbitrary DWORD.
|
|
*
|
|
* ExitProcF();
|
|
*
|
|
* Procedure returns a BOOL, where FALSE is an error.
|
|
*
|
|
* ExitOleProc();
|
|
*
|
|
* Procedure returns an HRESULT (named "hres").
|
|
*
|
|
* ExitOleProcPpv(ppvOut);
|
|
*
|
|
* Procedure returns an HRESULT (named "hres") and, on success,
|
|
* puts a new object in ppvOut.
|
|
*
|
|
* The ExitBenign* versions consider any error to be benign.
