* This file documents all the macros approved for use in windows source

* experts.
|
|
*
|
|
* DO NOT include this file directly. This file is include after
|
|
* specstrings.h. So we can undefine every possible old definition including
|
|
* private internal macros people should not be using, as well as macros from
|
|
* sal.h. Macros are redefined here in a way to cause syntax errors when used
|
|
* incorrectly during a normal build when specstrings.h is included and
|
|
* __SPECSTRINGS_STRICT_LEVEL is defined.
|
|
*
|
|
* There are several levels of strictness, each level includes the behavior of
|
|
* all previous levels.
|
|
*
|
|
* 0 - Disable strict checking
|
|
* 1 - Break on unapproved macros and misuse of statement
|
|
* macros such as __fallthrough (default)
|
|
* 2 - Deprecated some old macros that should not be used
|
|
* 3 - Use VS 2005 Source Annotation to make sure every macro
|
|
* is used in the right context. For example placing __in on a return
|
|
* parameter will result in an error.

|
* Introduction
|
|
*
|
|
* specstrings.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 must be placed before a function parameter's type or its return
|
|
* type. There are two basic classes of common 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 SpecStrings.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 | Optional | Parameters |
|
|
* |------------|------------|---------|--------|----------|---------------|
|
|
* | <> | <> | <> | <> | <> | <> |
|
|
* | _deref | _in | _ecount | _full | _opt | (size) |
|
|
* | _deref_opt | _out | _bcount | _part | | (size,length) |
|

|
|
* | | | | | | |
|
|
* |------------|------------|---------|--------|----------|---------------|
|
|
*
|
|
* Note: "<>" represents the empty string.
|
|
*
|
|
* 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.
|
|
*
|
|
* _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.
|
|
*
|
|
* 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.

* Buffer Annotation Examples
|
|
*
|
|
* LWSTDAPI_(BOOL) StrToIntExA(
|
|
* LPCSTR pszString, // No annotation required, const implies __in.
|
|
* DWORD dwFlags,
|
|
* __out int *piRet // A pointer whose dereference will be filled in.
|
|
* );
|
|
*
|
|
* void MyPaintingFunction(
|
|
* __in HWND hwndControl, // An initialized read-only parameter.
|
|
* __in_opt HDC hdcOptional, // An initialized read-only parameter that
|
|
* // might be NULL.
|
|
* __inout IPropertyStore *ppsStore // An initialized parameter that
|
|
* // may be freely used and modified.
|
|
* );
|
|
*
|
|
* LWSTDAPI_(BOOL) PathCompactPathExA(
|
|
* __out_ecount(cchMax) LPSTR pszOut, // A string buffer with cch elements
|
|
* // that will be '\0' terminated
|
|
* // on exit.
|
|
* LPCSTR pszSrc, // No annotation required,
|
|
* // const implies __in.
|
|
* UINT cchMax,
|
|
* DWORD dwFlags
|
|
* );
|
|
*
|
|
* HRESULT SHLocalAllocBytes(
|
|
* size_t cb,
|
|
* __deref_bcount(cb) T **ppv // A pointer whose dereference will be set
|
|
* // to an uninitialized buffer with cb bytes.
|
|
* );
|
|
*
|
|
* __inout_bcount_full(cb) : A buffer with cb elements that is fully
|
|
* initialized at entry and exit, and may be written to by this function.
|
|
*
|
|
* __out_ecount_part(count, *countOut) : A buffer with count elements that
|
|
* will be partially initialized by this function. The function indicates how
|
|
* much it initialized by setting *countOut.
|

* 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.
|
|
*
|
|
* _At_(expr, annotes) : annotation list annotes applies to target 'expr'
|
|
*
|
|
* _When_(expr, annotes) : annotation list annotes applies when 'expr' is true
|
|
*
|
|
* __success(expr) T 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.
|
|
*
|
|
* __out_awcount(expr, size) T *p : Pointer p is a buffer whose size may be
|
|
* given in either bytes or elements. If <expr> is true, this acts like
|
|
* __out_bcount. If <expr> is false, this acts like __out_ecount. This
|
|
* should only be used to annotate old APIs.
|
|
*
|
|
* __in_awcount(expr, size) T* p : Pointer p is a buffer whose size may be given
|
|
* in either bytes or elements. If <expr> is true, this acts like
|
|
* __in_bcount. If <expr> is false, this acts like __in_ecount. This should
|
|
* only be used to annotate old APIs.
|
|
*
|
|
* __nullterminated T* p : Pointer p is a buffer that may be read or written
|
|
* up to and including the first '\0' character or pointer. May be used on
|
|
* typedefs, which marks valid (properly initialized) instances of that type
|
|
* as being null-terminated.
|
|
*
|
|
* __nullnullterminated T* p : Pointer p is a buffer that may be read or
|
|
* written up to and including the first sequence of two '\0' characters or
|
|
* pointers. May be used on typedefs, which marks valid instances of that
|
|
* type as being double-null terminated.
|
|
*
|
|
* __reserved T v : Value v must be 0/NULL, reserved for future use.
|
|
*
|
|
* __checkReturn T f(); : Return value of f must not be ignored by callers
|
|
* of this function.
|
|
*
|
|
* __typefix(ctype) T v : Value v should be treated as an instance of ctype,
|
|
* rather than its declared type when considering validity.
|
|
*
|
|
* __override T f(); : Specify C#-style 'override' behaviour for overriding
|
|
* virtual methods.
|
|
*
|
|
* __callback T f(); : Function f can be used as a function pointer.
|
|
*
|
|
* __format_string T 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.
|
|
*
|
|
* __range(low_bnd, up_bnd) int f(): The return from the function "f" must
|
|
* be in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* __in_range(low_bnd, up_bnd) int i : Precondition that integer i must be
|
|
* in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* __out_range(low_bnd, up_bnd) int i : Postcondition that integer i must be
|
|
* in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* __deref_in_range(low_bnd, up_bnd) int* pi : Precondition that integer *pi
|
|
* must be in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* __deref_out_range(low_bnd, up_bnd) int* pi : Postcondition that integer
|
|
* *pi must be in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* __deref_inout_range(low_bnd, up_bnd) int* pi : Invariant that the integer
|
|
* *pi must be in the inclusive numeric range [low_bnd, up_bnd].
|
|
*
|
|
* The first argument of a range macro may also be a C relational operator
|
|
* (<,>,!=, ==, <=, >=).
|
|
*
|
|
* __range(rel_op, j) int f(): Postcondition that "f() rel_op j" must be
|
|
* true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __in_range(rel_op, j) int i : Precondition that "i rel_op j" must be
|
|
* true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __out_range(rel_op, j) int i : Postcondition that integer "i rel_op j"
|
|
* must be true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __deref_in_range(rel_op, j) int *pi : Precondition that "*pi rel_op j"
|
|
* must be true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __deref_out_range(rel_op, j) int *pi : Postcondition that "*pi rel_op j"
|
|
* must be true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __deref_inout_range(rel_op, j) int *pi : Invariant that "*pi rel_op j"
|
|
* must be true. Note that j may be a expression known only at runtime.
|
|
*
|
|
* __range_max(a, b) int f(): Postcondition f acts as 'max', returns larger
|
|
* of a and b. Note that a and b may be expressions known only at runtime.
|
|
*
|
|
* __range_min(a, b) int f(): Postcondition f acts as 'min', returns smaller
|
|
* of a and b. Note that a and b may be expressions known only at runtime.
|
|
*
|
|
* __in_bound int i : Precondition that integer i must be bound, but the
|
|
* exact range can't be specified at compile time. __in_range should be
|
|
* used if the range can be explicitly stated.
|
|
*
|
|
* __out_bound int i : Postcondition that integer i must be bound, but the
|
|
* exact range can't be specified at compile time. __out_range should be
|
|
* used if the range can be explicitly stated.
|
|
*
|
|
* __deref_out_bound int pi : Postcondition that integer *pi must be bound,
|
|
* but the exact range can't be specified at compile time.
|
|
* __deref_out_range should be used if the range can be explicitly stated.
|
|
*
|
|
* __assume_bound(expr); : Assume that the expression is bound to some known
|
|
* range. This can be used to suppress integer overflow warnings on integral
|
|
* expressions that are known to be bound due to reasons not explicit in the
|
|
* code. Use as a statement in the body of a function.
|
|
*
|
|
* __analysis_assume_nulltermianted(expr); : Assume that the expression is
|
|
* a null terminated buffer. Use this to suppress tool noise specific to
|
|
* nulltermination warnings, and capture deeper invariants tools can not
|
|
* discover.
|
|
*
|
|
* __allocator void f(): Function allocates memory using an integral size
|
|
* argument
|
|
*
|
|
* void myfree(__deallocate(Mem) void *p) : Memory is freed, no longer usable
|
|
* upon return, and p may not be null.
|
|
*
|
|
* void myfree(__deallocate_opt(Mem) void *p) : Memory is freed, no longer
|
|
* usable upon return, and p may be null.
|
|
*
|
|
* void free(__post_invalid void* x): Mark memory as untouchable when
|
|
* function returns.
|
|
*
|
|
* ----------------------------------------------------------------------------
|
|
* Advanced Annotation Examples
|
|
*
|
|
* __success(return == TRUE) LWSTDAPI_(BOOL)
|
|
* PathCanonicalizeA(__out_ecount(MAX_PATH) LPSTR pszBuf, LPCSTR pszPath);
|
|
* // pszBuf is only guaranteed to be null-terminated when TRUE is returned.
|
|
*
|
|
* // Initialized LPWSTRs are null-terminated strings.
|
|
* typedef __nullterminated WCHAR* LPWSTR;
|
|
*
|
|
* __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.

|
* structure annotations by one choosing an element from each column of
|
|
* this table to build a composite annotation.

* Note that empty represents the empty string. Sometime arguments need
|
|
* to be "floated" to the left to give us a valid annotation name. For
|
|
* example the naive combination __field_ecount(size)_opt is actually
|
|
* written as __field_ecount_opt(size). Not all possible combinations
|
|

|
|
*Summary of Elements
|
|
*
|
|
* Selector
|
|
*
|
|
* __field
|
|
* The annotation should only be placed in front
|
|
* of data members of structures and classes. The
|
|
* data members are pointers to a block of data.
|
|
* The annotations describe properties about the
|
|
* size of the block of data. This can be used for
|
|
*
|
|
* __struct
|
|
* The annotation should only be placed at the
|
|
* beginning of the definition of a structure or
|
|
* class. These annotations are used when a struct
|
|
* or class is used as a "header" that is
|
|
* allocated inline with a block of data and there
|
|
* is no apparent field that represents the tail
|
|
* end of the structure.
|
|
*
|
|
* Units
|
|
*
|
|
* _ecount
|
|
* All size and initialization values are in terms
|
|
* of elements of the appropriate type
|
|
*
|
|
* _bcount
|
|
* All size and initialization values are in terms
|
|
* of raw byte sizes.
|
|
*
|
|
* _xcount
|
|
* The size or initialization values cannot be
|
|
* properly expressed as a simple byte or element
|
|
* count, and instead a place holder is used to
|
|
* document the relationship.
|
|
*
|
|
* Size/Init
|
|
* All the size/init expressions can contain references to
|
|
* other fields in the struct or class.
|
|
*
|
|
* (size)
|
|
* The size of the buffer is determined by the
|
|
* expression size. Unless, the type of the buffer
|
|
* provides more information nothing is know about
|
|
* how much of this data is initialized. For
|
|
* example, if the data member happens to be a
|
|
* string type such as LPSTR. It is assumed that
|
|
* the data is initialized to the first '\0'.
|
|
*
|
|
* _full(size)
|
|
* The size of the buffer is determined by the
|
|
* expression size and all the data in the buffer
|
|
* is guaranteed to be initialized.
|
|
*
|
|
* _part(size,init)
|
|
* The size of the buffer is determined by the
|
|
* expression size and all the data in the buffer
|
|
* is guaranteed to be initialized up to init
|
|
* elements or bytes.
|
|
*
|
|
* Optional
|
|
*
|
|
* empty
|
|
* The pointer to the block of memory is never
|
|
* NULL
|
|
*
|
|
* _opt
|
|
* The pointer to the block of memory is may be
|
|
* NULL
