//*****************************************************************************
// Behavioral setup (error handling macro configuration)
//*****************************************************************************
// Set any of the following macros to the values given below before including Result.h to
// control the error handling macro's trade-offs between diagnostics and performance

// RESULT_DIAGNOSTICS_LEVEL
// This define controls the level of diagnostic instrumentation that is built into the binary as a
// byproduct of using the macros.  The amount of diagnostic instrumentation that is supplied is
// a trade-off between diagnosibility of issues and code size and performance.  The modes are:
//      0   - No diagnostics, smallest & fastest (subject to tail-merge)
//      1   - No diagnostics, unique call sites for each macro (defeat's tail-merge)
//      2   - Line number
//      3   - Line number + source filename
//      4   - Line number + source filename + function name
//      5   - Line number + source filename + function name + code within the macro
// By default, mode 3 is used in free builds and mode 5 is used in checked builds.  Note that the
// _ReturnAddress() will always be available through all modes when possible.

// RESULT_INCLUDE_CALLER_RETURNADDRESS
// This controls whether or not the _ReturnAddress() of the function that includes the macro will
// be reported to telemetry.  Note that this is in addition to the _ReturnAddress() of the actual
// macro position (which is always reported).  The values are:
//      0   - The address is not included
//      1   - The address is included
// The default value is '1'.

// RESULT_INLINE_ERROR_TESTS
// For conditional macros (other than RETURN_XXX), this controls whether branches will be evaluated
// within the call containing the macro or will be forced into the function called by the macros.
// Pushing branching into the called function reduces code size and the number of unique branches
// evaluated, but increases the instruction count executed per macro.
//      0   - Branching will not happen inline to the macros
//      1   - Branching is pushed into the calling function via __forceinline
// The default value is '1'.  Note that XXX_MSG functions are always effectively mode '0' due to the
// compiler's unwillingness to inline var-arg functions.

// RESULT_DIAGNOSTICS_LEVEL_FAIL_FAST
// RESULT_INCLUDE_CALLER_RETURNADDRESS_FAIL_FAST
// RESULT_INLINE_ERROR_TESTS_FAIL_FAST
// These defines are identical to those above in form/function, but only applicable to fail fast error
// handling allowing a process to have different diagnostic information and performance characteristics
// for fail fast than for other error handling given the different reporting infrastructure (Watson
// vs Telemetry).

// Set the default diagnostic mode
// Note that RESULT_DEBUG_INFO and RESULT_SUPPRESS_DEBUG_INFO are older deprecated models of controlling mode

    //! A lambda-based exception guard that can identify the origin of unknown exceptions and can vary the supported exception types.
    //! Functionally this is nearly identical to the corresponding @ref ResultFromException function with the exception
    //! that it utilizes structured exception handling internally to be able to terminate at the point where a unknown
    //! exception is thrown, rather than after that unknown exception has been unwound.  Though less efficient, this leads
    //! to a better debugging experience when analyzing unknown exceptions.
    //!
    //! For example:
    //! ~~~~
    //! hr = wil::ResultFromExceptionDebug(WI_DIAGNOSTICS_INFO, [&]
    //! {
    //!     FunctionWhichMayThrow();
    //! });
    //! ~~~~
    //! Assume FunctionWhichMayThrow() has a bug in it where it accidentally does a `throw E_INVALIDARG;`.  This ends up
    //! throwing a `long` as an exception object which is not what the caller intended.  The normal @ref ResultFromException
    //! would fail-fast when this is encountered, but it would do so AFTER FunctionWhichMayThrow() is already off of the
    //! stack and has been unwound.  Because SEH is used for ResultFromExceptionDebug, the fail-fast occurs with everything
    //! leading up to and including the `throw INVALIDARG;` still on the stack (and easily debuggable).
    //!
    //! The penalty paid for using this, however, is efficiency.  It's far less efficient as a general pattern than either
    //! using ResultFromException directly or especially using try with CATCH_ macros directly.  Still it's helpful to deploy
    //! selectively to isolate issues a component may be having with unknown/unhandled exceptions.
    //!
    //! The ability to vary the SupportedExceptions that this routine provides adds the ability to track down unexpected
    //! exceptions not falling into the supported category easily through fail-fast.  For example, by not supporting any
    //! exception, you can use this function to quickly add an exception guard that will fail-fast any exception at the point
    //! the exception occurs (the throw) in a codepath where the origination of unknown exceptions need to be tracked down.
    //!
    //! Also see @ref ResultFromExceptionDebugNoStdException.  It functions almost identically, but also will fail-fast and stop
    //! on std::exception based exceptions (but not Platform::Exception^ or wil::ResultException).  Using this can help isolate
    //! where an unexpected exception is being generated from.
    //! @param diagnostics  Always pass WI_DIAGNOSTICS_INFO as the first parameter
    //! @param supported    What kind of exceptions you want to support
    //! @param functor      A lambda that accepts no parameters; any return value is ignored
    //! @return             S_OK on success (no exception thrown) or an error based upon the exception thrown
