   The comments in this file are intended to give basic understanding of
   the usage of SAL, the Microsoft Source Code Annotation Language.
   For more details, please see http://go.microsoft.com/fwlink/?LinkID=242134

   The macros are defined in 3 layers, plus the structural set:

   _In_/_Out_/_Ret_ Layer:
   ----------------------
   This layer provides the highest abstraction and its macros should be used
   in most cases. These macros typically start with:
      _In_     : input parameter to a function, unmodified by called function
      _Out_    : output parameter, written to by called function, pointed-to
                 location not expected to be initialized prior to call
      _Outptr_ : like _Out_ when returned variable is a pointer type
                 (so param is pointer-to-pointer type). Called function
                 provides/allocated space.
      _Outref_ : like _Outptr_, except param is reference-to-pointer type.
      _Inout_  : inout parameter, read from and potentially modified by
                 called function.
      _Ret_    : for return values
      _Field_  : class/struct field invariants
   For common usage, this class of SAL provides the most concise annotations.
   Note that _In_/_Out_/_Inout_/_Outptr_ annotations are designed to be used
   with a parameter target. Using them with _At_ to specify non-parameter
   targets may yield unexpected results.

   This layer also includes a number of other properties that can be specified
   to extend the ability of code analysis, most notably:
      -- Designating parameters as format strings for printf/scanf/scanf_s
      -- Requesting stricter type checking for C enum parameters

   _Pre_/_Post_ Layer:
   ------------------
   The macros of this layer only should be used when there is no suitable macro
   in the _In_/_Out_ layer. Its macros start with _Pre_ or _Post_.
   This layer provides the most flexibility for annotations.

   Implementation Abstraction Layer:
   --------------------------------
   Macros from this layer should never be used directly. The layer only exists
   to hide the implementation of the annotation macros.

   Structural Layer:
   ----------------
   These annotations, like _At_ and _When_, are used with annotations from
   any of the other layers as modifiers, indicating exactly when and where
   the annotations apply.


   Common syntactic conventions:
   ----------------------------

   Usage:
   -----
   _In_, _Out_, _Inout_, _Pre_, _Post_, are for formal parameters.
   _Ret_, _Deref_ret_ must be used for return values.

   Nullness:
   --------
   If the parameter can be NULL as a precondition to the function, the
   annotation contains _opt. If the macro does not contain '_opt' the
   parameter cannot be NULL.

   If an out/inout parameter returns a null pointer as a postcondition, this is
   indicated by _Ret_maybenull_ or _result_maybenull_. If the macro is not
   of this form, then the result will not be NULL as a postcondition.
     _Outptr_ - output value is not NULL
     _Outptr_result_maybenull_ - output value might be NULL

   String Type:
   -----------
   _z: NullTerminated string
   for _In_ parameters the buffer must have the specified stringtype before the call
   for _Out_ parameters the buffer must have the specified stringtype after the call
   for _Inout_ parameters both conditions apply

   Extent Syntax:
   -------------
   Buffer sizes are expressed as element counts, unless the macro explicitly
   contains _byte_ or _bytes_. Some annotations specify two buffer sizes, in
   which case the second is used to indicate how much of the buffer is valid
   as a postcondition. This table outlines the precondition buffer allocation
   size, precondition number of valid elements, postcondition allocation size,
   and postcondition number of valid elements for representative buffer size
   annotations:
                                     Pre    |  Pre    |  Post   |  Post
                                     alloc  |  valid  |  alloc  |  valid
      Annotation                     elems  |  elems  |  elems  |  elems
      ----------                     ------------------------------------
      _In_reads_(s)                    s    |   s     |   s     |   s
      _Inout_updates_(s)               s    |   s     |   s     |   s
      _Inout_updates_to_(s,c)          s    |   s     |   s     |   c
      _Out_writes_(s)                  s    |   0     |   s     |   s
      _Out_writes_to_(s,c)             s    |   0     |   s     |   c
      _Outptr_result_buffer_(s)        ?    |   ?     |   s     |   s
      _Outptr_result_buffer_to_(s,c)   ?    |   ?     |   s     |   c

   For the _Outptr_ annotations, the buffer in question is at one level of
   dereference. The called function is responsible for supplying the buffer.

   Success and failure:
   -------------------
   The SAL concept of success allows functions to define expressions that can
   be tested by the caller, which if it evaluates to non-zero, indicates the
   function succeeded, which means that its postconditions are guaranteed to
   hold.  Otherwise, if the expression evaluates to zero, the function is
   considered to have failed, and the postconditions are not guaranteed.

   The success criteria can be specified with the _Success_(expr) annotation:
     _Success_(return != FALSE) BOOL
     PathCanonicalizeA(_Out_writes_(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath) :
        pszBuf is only guaranteed to be NULL-terminated when TRUE is returned,
        and FALSE indiates failure. In common practice, callers check for zero
        vs. non-zero returns, so it is preferable to express the success
        criteria in terms of zero/non-zero, not checked for exactly TRUE.

   Functions can specify that some postconditions will still hold, even when
   the function fails, using _On_failure_(anno-list), or postconditions that
   hold regardless of success or failure using _Always_(anno-list).

   The annotation _Return_type_success_(expr) may be used with a typedef to
   give a default _Success_ criteria to all functions returning that type.
   This is the case for common Windows API status types, including
   HRESULT and NTSTATUS.  This may be overridden on a per-function basis by
   specifying a _Success_ annotation locally.

//    _Outptr_opt_ - describes parameters that are allowed to be NULL.
//    _Outptr_*_result_maybenull_ - describes parameters where the called function might return NULL to the caller.
//
//    Example:

//    Callers:
//       MyFunc(NULL, NULL);           // error: parameter 2, ppData2, should not be NULL
//       MyFunc(&pData1, &pData2);     // ok: both non-NULL

#pragma region Input Buffer SAL 1 compatibility macros

/*==========================================================================

   This section contains definitions for macros defined for VS2010 and earlier.
   Usage of these macros is still supported, but the SAL 2 macros defined above
   are recommended instead.  This comment block is retained to assist in
   understanding SAL that still uses the older syntax.

   The macros are defined in 3 layers:

   _In_\_Out_ Layer:
   ----------------
   This layer provides the highest abstraction and its macros should be used
   in most cases. Its macros start with _In_, _Out_ or _Inout_. For the
   typical case they provide the most concise annotations.

   _Pre_\_Post_ Layer:
   ------------------
   The macros of this layer only should be used when there is no suitable macro
   in the _In_\_Out_ layer. Its macros start with _Pre_, _Post_, _Ret_,
   _Deref_pre_ _Deref_post_ and _Deref_ret_. This layer provides the most
   flexibility for annotations.

   Implementation Abstraction Layer:
   --------------------------------
   Macros from this layer should never be used directly. The layer only exists
   to hide the implementation of the annotation macros.


   Annotation Syntax:
   |--------------|----------|----------------|-----------------------------|
   |   Usage      | Nullness | ZeroTerminated |  Extent                     |
   |--------------|----------|----------------|-----------------------------|
   | _In_         | <>       | <>             | <>                          |
   | _Out_        | opt_     | z_             | [byte]cap_[c_|x_]( size )   |
   | _Inout_      |          |                | [byte]count_[c_|x_]( size ) |
   | _Deref_out_  |          |                | ptrdiff_cap_( ptr )         |
   |--------------|          |                | ptrdiff_count_( ptr )       |
   | _Ret_        |          |                |                             |
   | _Deref_ret_  |          |                |                             |
   |--------------|          |                |                             |
   | _Pre_        |          |                |                             |
   | _Post_       |          |                |                             |
   | _Deref_pre_  |          |                |                             |
   | _Deref_post_ |          |                |                             |
   |--------------|----------|----------------|-----------------------------|

   Usage:
   -----
   _In_, _Out_, _Inout_, _Pre_, _Post_, _Deref_pre_, _Deref_post_ are for
   formal parameters.
   _Ret_, _Deref_ret_ must be used for return values.

   Nullness:
   --------
   If the pointer can be NULL the annotation contains _opt. If the macro
   does not contain '_opt' the pointer may not be NULL.

   String Type:
   -----------
   _z: NullTerminated string
   for _In_ parameters the buffer must have the specified stringtype before the call
   for _Out_ parameters the buffer must have the specified stringtype after the call
   for _Inout_ parameters both conditions apply

   Extent Syntax:
   |------|---------------|---------------|
   | Unit | Writ\Readable | Argument Type |
   |------|---------------|---------------|
   |  <>  | cap_          | <>            |
   | byte | count_        | c_            |
   |      |               | x_            |
   |------|---------------|---------------|

   'cap' (capacity) describes the writable size of the buffer and is typically used
   with _Out_. The default unit is elements. Use 'bytecap' if the size is given in bytes
   'count' describes the readable size of the buffer and is typically used with _In_.
   The default unit is elements. Use 'bytecount' if the size is given in bytes.
   
   Argument syntax for cap_, bytecap_, count_, bytecount_:
   (<parameter>|return)[+n]  e.g. cch, return, cb+2
   
   If the buffer size is a constant expression use the c_ postfix.
   E.g. cap_c_(20), count_c_(MAX_PATH), bytecount_c_(16)

   If the buffer size is given by a limiting pointer use the ptrdiff_ versions
   of the macros.

   If the buffer size is neither a parameter nor a constant expression use the x_
   postfix. e.g. bytecount_x_(num*size) x_ annotations accept any arbitrary string.
   No analysis can be done for x_ annotations but they at least tell the tool that
   the buffer has some sort of extent description. x_ annotations might be supported
   by future compiler versions.

// Naming conventions:
// A symbol the begins with _SA_ is for the machinery of creating any
// annotations; many of those come from sourceannotations.h in the case
// of attributes.

// A symbol that ends with _impl is the very lowest level macro.  It is
// not required to be a legal standalone annotation, and in the case
// of attribute annotations, usually is not.  (In the case of some declspec
// annotations, it might be, but it should not be assumed so.)  Those
// symols will be used in the _PreN..., _PostN... and _RetN... annotations 
// to build up more complete annotations.

// A symbol ending in _impl_ is reserved to the implementation as well,
// but it does form a complete annotation; usually they are used to build
// up even higher level annotations.

 Introduction

 sal.h provides a set of annotations to describe how a function uses its
 parameters - the assumptions it makes about them, and the guarantees it makes
 upon finishing.

 Annotations may be placed before either a function parameter's type or its return
 type, and describe the function's behavior regarding the parameter or return value.
 There are two classes of annotations: buffer annotations and advanced annotations.
 Buffer annotations describe how functions use their pointer parameters, and
 advanced annotations either describe complex/unusual buffer behavior, or provide
 additional information about a parameter that is not otherwise expressible.

 -------------------------------------------------------------------------------
 Buffer Annotations

 The most important annotations in sal.h provide a consistent way to annotate
 buffer parameters or return values for a function. Each of these annotations describes
 a single buffer (which could be a string, a fixed-length or variable-length array,
 or just a pointer) that the function interacts with: where it is, how large it is,
 how much is initialized, and what the function does with it.

 The appropriate macro for a given buffer can be constructed using the table below.
 Just pick the appropriate values from each category, and combine them together
 with a leading underscore. Some combinations of values do not make sense as buffer
 annotations. Only meaningful annotations can be added to your code; for a list of
 these, see the buffer annotation definitions section.

 Only a single buffer annotation should be used for each parameter.

 |------------|------------|---------|--------|----------|----------|---------------|
 |   Level    |   Usage    |  Size   | Output | NullTerm | Optional |  Parameters   |
 |------------|------------|---------|--------|----------|----------|---------------|
 | <>         | <>         | <>      | <>     | _z       | <>       | <>            |

 |------------|------------|---------|--------|----------|----------|---------------|

 Level: Describes the buffer pointer's level of indirection from the parameter or
          return value 'p'.

 <>         : p is the buffer pointer.
 _deref     : *p is the buffer pointer. p must not be NULL.
 _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the rest of
                the annotation is ignored.

 Usage: Describes how the function uses the buffer.

 <>     : The buffer is not accessed. If used on the return value or with _deref, the
            function will provide the buffer, and it will be uninitialized at exit.
            Otherwise, the caller must provide the buffer. This should only be used
            for alloc and free functions.
 _in    : The function will only read from the buffer. The caller must provide the
            buffer and initialize it. Cannot be used with _deref.
 _out   : The function will only write to the buffer. If used on the return value or
            with _deref, the function will provide the buffer and initialize it.
            Otherwise, the caller must provide the buffer, and the function will
            initialize it.
 _inout : The function may freely read from and write to the buffer. The caller must
            provide the buffer and initialize it. If used with _deref, the buffer may
            be reallocated by the function.

 Size: Describes the total size of the buffer. This may be less than the space actually
         allocated for the buffer, in which case it describes the accessible amount.

 <>      : No buffer size is given. If the type specifies the buffer size (such as
             with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is one
             element long. Must be used with _in, _out, or _inout.
 _ecount : The buffer size is an explicit element count.
 _bcount : The buffer size is an explicit byte count.

 Output: Describes how much of the buffer will be initialized by the function. For
           _inout buffers, this also describes how much is initialized at entry. Omit this
           category for _in buffers; they must be fully initialized by the caller.

 <>    : The type specifies how much is initialized. For instance, a function initializing
           an LPWSTR must NULL-terminate the string.
 _full : The function initializes the entire buffer.
 _part : The function initializes part of the buffer, and explicitly indicates how much.

 NullTerm: States if the present of a '\0' marks the end of valid elements in the buffer.
 _z    : A '\0' indicated the end of the buffer
 _nz     : The buffer may not be null terminated and a '\0' does not indicate the end of the
          buffer.
 Optional: Describes if the buffer itself is optional.

 <>   : The pointer to the buffer must not be NULL.
 _opt : The pointer to the buffer might be NULL. It will be checked before being dereferenced.

 Parameters: Gives explicit counts for the size and length of the buffer.

 <>            : There is no explicit count. Use when neither _ecount nor _bcount is used.
 (size)        : Only the buffer's total size is given. Use with _ecount or _bcount but not _part.
 (size,length) : The buffer's total size and initialized length are given. Use with _ecount_part
                   and _bcount_part.

 Advanced Annotations

 Advanced annotations describe behavior that is not expressible with the regular
 buffer macros. These may be used either to annotate buffer parameters that involve
 complex or conditional behavior, or to enrich existing annotations with additional
 information.

 __success(expr) f :
     <expr> indicates whether function f succeeded or not. If <expr> is true at exit,
     all the function's guarantees (as given by other annotations) must hold. If <expr>
     is false at exit, the caller should not expect any of the function's guarantees
     to hold. If not used, the function must always satisfy its guarantees. Added
     automatically to functions that indicate success in standard ways, such as by
     returning an HRESULT.

 __nullterminated p :
     Pointer p is a buffer that may be read or written up to and including the first
     NULL character or pointer. May be used on typedefs, which marks valid (properly
     initialized) instances of that type as being NULL-terminated.

 __nullnullterminated p :
     Pointer p is a buffer that may be read or written up to and including the first
     sequence of two NULL characters or pointers. May be used on typedefs, which marks
     valid instances of that type as being double-NULL terminated.

 __reserved v :
     Value v must be 0/NULL, reserved for future use.

 __checkReturn v :
     Return value v must not be ignored by callers of this function.

 __typefix(ctype) v :
     Value v should be treated as an instance of ctype, rather than its declared type.

 __override f :
     Specify C#-style 'override' behaviour for overriding virtual methods.

 __callback f :
     Function f can be used as a function pointer.

 __format_string p :
     Pointer p is a string that contains % markers in the style of printf.

 __blocksOn(resource) f :
     Function f blocks on the resource 'resource'.

 __fallthrough :
     Annotates switch statement labels where fall-through is desired, to distinguish
     from forgotten break statements.

 -------------------------------------------------------------------------------
 Advanced Annotation Examples

 __success(return != FALSE) LWSTDAPI_(BOOL) 
 PathCanonicalizeA(__out_ecount(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath) :
    pszBuf is only guaranteed to be NULL-terminated when TRUE is returned.

 typedef __nullterminated WCHAR* LPWSTR : Initialized LPWSTRs are NULL-terminated strings.

 __out_ecount(cch) __typefix(LPWSTR) void *psz : psz is a buffer parameter which will be
     a NULL-terminated WCHAR string at exit, and which initially contains cch WCHARs.
