    39   Introduction
    40  
    41   sal.h provides a set of annotations to describe how a function uses its
    42   parameters - the assumptions it makes about them, and the guarantees it makes
    43   upon finishing.
    44  
    45   Annotations may be placed before either a function parameter's type or its return
    46   type, and describe the function's behavior regarding the parameter or return value.
    47   There are two classes of annotations: buffer annotations and advanced annotations.
    48   Buffer annotations describe how functions use their pointer parameters, and
    49   advanced annotations either describe complex/unusual buffer behavior, or provide
    50   additional information about a parameter that is not otherwise expressible.
    51  
    52   -------------------------------------------------------------------------------
    53   Buffer Annotations
    54  
    55   The most important annotations in sal.h provide a consistent way to annotate
    56   buffer parameters or return values for a function. Each of these annotations describes
    57   a single buffer (which could be a string, a fixed-length or variable-length array,
    58   or just a pointer) that the function interacts with: where it is, how large it is,
    59   how much is initialized, and what the function does with it.
    60  
    61   The appropriate macro for a given buffer can be constructed using the table below.
    62   Just pick the appropriate values from each category, and combine them together
    63   with a leading underscore. Some combinations of values do not make sense as buffer
    64   annotations. Only meaningful annotations can be added to your code; for a list of
    65   these, see the buffer annotation definitions section.
    66  
    67   Only a single buffer annotation should be used for each parameter.

    78  
    79   Level: Describes the buffer pointer's level of indirection from the parameter or
    80            return value 'p'.
    81  
    82   <>         : p is the buffer pointer.
    83   _deref     : *p is the buffer pointer. p must not be NULL.
    84   _deref_opt : *p may be the buffer pointer. p may be NULL, in which case the rest of
    85                  the annotation is ignored.
    86  
    87   Usage: Describes how the function uses the buffer.
    88  
    89   <>     : The buffer is not accessed. If used on the return value or with _deref, the
    90              function will provide the buffer, and it will be uninitialized at exit.
    91              Otherwise, the caller must provide the buffer. This should only be used
    92              for alloc and free functions.
    93   _in    : The function will only read from the buffer. The caller must provide the
    94              buffer and initialize it. Cannot be used with _deref.
    95   _out   : The function will only write to the buffer. If used on the return value or
    96              with _deref, the function will provide the buffer and initialize it.
    97              Otherwise, the caller must provide the buffer, and the function will
    98              initialize it.
    99   _inout : The function may freely read from and write to the buffer. The caller must
   100              provide the buffer and initialize it. If used with _deref, the buffer may
   101              be reallocated by the function.
   102  
   103   Size: Describes the total size of the buffer. This may be less than the space actually
   104           allocated for the buffer, in which case it describes the accessible amount.
   105  
   106   <>      : No buffer size is given. If the type specifies the buffer size (such as
   107               with LPSTR and LPWSTR), that amount is used. Otherwise, the buffer is one
   108               element long. Must be used with _in, _out, or _inout.
   109   _ecount : The buffer size is an explicit element count.
   110   _bcount : The buffer size is an explicit byte count.
   111  
   112   Output: Describes how much of the buffer will be initialized by the function. For
   113             _inout buffers, this also describes how much is initialized at entry. Omit this
   114             category for _in buffers; they must be fully initialized by the caller.
   115  
   116   <>    : The type specifies how much is initialized. For instance, a function initializing
   117             an LPWSTR must NULL-terminate the string.
   118   _full : The function initializes the entire buffer.
   119   _part : The function initializes part of the buffer, and explicitly indicates how much.
   120  
   121   NullTerm: States if the present of a '\0' marks the end of valid elements in the buffer.
   122   _z    : A '\0' indicated the end of the buffer
   123   _nz	 : The buffer may not be null terminated and a '\0' does not indicate the end of the
   124            buffer.
   125   Optional: Describes if the buffer itself is optional.
   126  
   127   <>   : The pointer to the buffer must not be NULL.
   128   _opt : The pointer to the buffer might be NULL. It will be checked before being dereferenced.
   129  
   130   Parameters: Gives explicit counts for the size and length of the buffer.
   131  
   132   <>            : There is no explicit count. Use when neither _ecount nor _bcount is used.
   133   (size)        : Only the buffer's total size is given. Use with _ecount or _bcount but not _part.
   134   (size,length) : The buffer's total size and initialized length are given. Use with _ecount_part
   135                     and _bcount_part.

   149       __inout IPropertyStore *ppsStore     -- An initialized parameter that may be freely used
   150                                            --   and modified.
   151   );
   152  
   153   LWSTDAPI_(BOOL) PathCompactPathExA(
   154       __out_ecount(cchMax) LPSTR pszOut,   -- A string buffer with cch elements that will
   155                                            --   be NULL terminated on exit.
   156       LPCSTR pszSrc,                       -- No annotation required, const implies __in.
   157       UINT cchMax,
   158       DWORD dwFlags
   159   );
   160  
   161   HRESULT SHLocalAllocBytes(
   162       size_t cb,
   163       __deref_bcount(cb) T **ppv           -- A pointer whose dereference will be set to an
   164                                            --   uninitialized buffer with cb bytes.
   165   );
   166  
   167   __inout_bcount_full(cb) : A buffer with cb elements that is fully initialized at
   168       entry and exit, and may be written to by this function.
   169  
   170   __out_ecount_part(count, *countOut) : A buffer with count elements that will be
   171       partially initialized by this function. The function indicates how much it
   172       initialized by setting *countOut.
   173  
   174   -------------------------------------------------------------------------------
   175   Advanced Annotations
   176  
   177   Advanced annotations describe behavior that is not expressible with the regular
   178   buffer macros. These may be used either to annotate buffer parameters that involve
   179   complex or conditional behavior, or to enrich existing annotations with additional
   180   information.
   181  
   182   __success(expr) f :
   183       <expr> indicates whether function f succeeded or not. If <expr> is true at exit,
   184       all the function's guarantees (as given by other annotations) must hold. If <expr>
   185       is false at exit, the caller should not expect any of the function's guarantees
   186       to hold. If not used, the function must always satisfy its guarantees. Added
   187       automatically to functions that indicate success in standard ways, such as by
   188       returning an HRESULT.
   189  
   190   __nullterminated p :
   191       Pointer p is a buffer that may be read or written up to and including the first
   192       NULL character or pointer. May be used on typedefs, which marks valid (properly
   193       initialized) instances of that type as being NULL-terminated.
   194  
   195   __nullnullterminated p :
   196       Pointer p is a buffer that may be read or written up to and including the first
   197       sequence of two NULL characters or pointers. May be used on typedefs, which marks
   198       valid instances of that type as being double-NULL terminated.
   199  
   200   __reserved v :
   201       Value v must be 0/NULL, reserved for future use.
   202  
   203   __checkReturn v :
   204       Return value v must not be ignored by callers of this function.
   205  
   206   __typefix(ctype) v :
   207       Value v should be treated as an instance of ctype, rather than its declared type.
   208  
   209   __override f :
   210       Specify C#-style 'override' behaviour for overriding virtual methods.
   211  
   212   __callback f :
   213       Function f can be used as a function pointer.
   214  
   215   __format_string p :
   216       Pointer p is a string that contains % markers in the style of printf.
   217  
   218   __blocksOn(resource) f :
   219       Function f blocks on the resource 'resource'.
   220  
   221   __fallthrough :
   222       Annotates switch statement labels where fall-through is desired, to distinguish
   223       from forgotten break statements.
   224  
   225   -------------------------------------------------------------------------------
   226   Advanced Annotation Examples
   227  
   228   __success(return == TRUE) LWSTDAPI_(BOOL) 
   229   PathCanonicalizeA(__out_ecount(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath) :
   230       pszBuf is only guaranteed to be NULL-terminated when TRUE is returned.
   231  
   232   typedef __nullterminated WCHAR* LPWSTR : Initialized LPWSTRs are NULL-terminated strings.
   233  
   234   __out_ecount(cch) __typefix(LPWSTR) void *psz : psz is a buffer parameter which will be
   235       a NULL-terminated WCHAR string at exit, and which initially contains cch WCHARs.

   419       Given a set of annotations Q containing __exceptthat maybeP, the effect of

   426                   the implicit notnull annotation implied by __valid on

   429        Example 2: __valid __deref __exceptthat __maybenull on an int **p means
   430                   that p is not null (implied by valid), but the elements
