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: 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.

|
|
HRESULT SHLocalAllocBytes(

|
|||
|
|
);
|
|||
|
|
|
|||
|

__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.
|
|||
|
|
|
|||
|
|
__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.
|
|||
|
|

|
|
__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.
|
|||
|
|

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

|
|
the except clause is to erase any P or notP annotations (explicit or

implied) within Q at the same level of dereferencing that the except

|
clause appears, and to replace it with maybeP.

Example 1: __valid __exceptthat __maybenull on a pointer p means that the
|

|

pointer may be null, and is otherwise valid, thus overriding
|
|||
|
|
the implicit notnull annotation implied by __valid on
|
|||
|
|
pointers.
|

|
|
|

Example 2: __valid __deref __exceptthat __maybenull on an int **p means

that p is not null (implied by valid), but the elements
