173 or ungetwc() that have not subsequently been read from the

444/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
445 for FUNCTION which will then trigger a compiler warning containing
446 the text of "literal string" anywhere that function is called, if
447 supported by the compiler. If the compiler does not support this
448 feature, the macro expands to an unused extern declaration.
449
450 _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
451 attribute used in _GL_WARN_ON_USE. If the compiler does not support
452 this feature, it expands to empty.
453
454 These macros are useful for marking a function as a potential
455 portability trap, with the intent that "literal string" include
456 instructions on the replacement function that should be used
457 instead.
458 _GL_WARN_ON_USE is for functions with 'extern' linkage.
459 _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
460 linkage.
461
462 However, one of the reasons that a function is a portability trap is
463 if it has the wrong signature. Declaring FUNCTION with a different
464 signature in C is a compilation error, so this macro must use the
465 same type as any existing declaration so that programs that avoid
466 the problematic FUNCTION do not fail to compile merely because they
467 included a header that poisoned the function. But this implies that
468 _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
469 have a declaration. Use of this macro implies that there must not
470 be any other macro hiding the declaration of FUNCTION; but
471 undefining FUNCTION first is part of the poisoning process anyway
472 (although for symbols that are provided only via a macro, the result
473 is a compilation error rather than a warning containing
474 "literal string"). Also note that in C++, it is only safe to use if
475 FUNCTION has no overloads.
476
477 For an example, it is possible to poison 'getline' by:
478 - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
479 [getline]) in configure.ac, which potentially defines
480 HAVE_RAW_DECL_GETLINE
481 - adding this code to a header that wraps the system <stdio.h>:
482 #undef getline
483 #if HAVE_RAW_DECL_GETLINE

489 possible to write a wrapper accessor function, and poison that

492 the developer about their portability problem is still achieved):

20/* Pre-processor macros which act as parameters:
21
22 DYNARRAY_STRUCT
23 The struct tag of dynamic array to be defined.
24 DYNARRAY_ELEMENT
25 The type name of the element type. Elements are copied
26 as if by memcpy, and can change address as the dynamic
27 array grows.
28 DYNARRAY_PREFIX
29 The prefix of the functions which are defined.
30
31 The following parameters are optional:
32
33 DYNARRAY_ELEMENT_FREE
34 DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
35 contents of elements. E is of type DYNARRAY_ELEMENT *.
36 DYNARRAY_ELEMENT_INIT
37 DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
38 element. E is of type DYNARRAY_ELEMENT *.
39 If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
40 defined, new elements are automatically zero-initialized.
41 Otherwise, new elements have undefined contents.
42 DYNARRAY_INITIAL_SIZE
43 The size of the statically allocated array (default:
44 at least 2, more elements if they fit into 128 bytes).
45 Must be a preprocessor constant. If DYNARRAY_INITIAL_SIZE is 0,
46 there is no statically allocated array at, and all non-empty
47 arrays are heap-allocated.
48 DYNARRAY_FINAL_TYPE
49 The name of the type which holds the final array. If not
50 defined, is PREFIX##finalize not provided. DYNARRAY_FINAL_TYPE
51 must be a struct type, with members of type DYNARRAY_ELEMENT and
52 size_t at the start (in this order).
53
54 These macros are undefined after this header file has been
55 included.
56
57 The following types are provided (their members are private to the
58 dynarray implementation):
59
60 struct DYNARRAY_STRUCT
61
62 The following functions are provided:
63
64 void DYNARRAY_PREFIX##init (struct DYNARRAY_STRUCT *);
65 void DYNARRAY_PREFIX##free (struct DYNARRAY_STRUCT *);
66 bool DYNARRAY_PREFIX##has_failed (const struct DYNARRAY_STRUCT *);
67 void DYNARRAY_PREFIX##mark_failed (struct DYNARRAY_STRUCT *);
68 size_t DYNARRAY_PREFIX##size (const struct DYNARRAY_STRUCT *);
69 DYNARRAY_ELEMENT *DYNARRAY_PREFIX##begin (const struct DYNARRAY_STRUCT *);
70 DYNARRAY_ELEMENT *DYNARRAY_PREFIX##end (const struct DYNARRAY_STRUCT *);
71 DYNARRAY_ELEMENT *DYNARRAY_PREFIX##at (struct DYNARRAY_STRUCT *, size_t);
72 void DYNARRAY_PREFIX##add (struct DYNARRAY_STRUCT *, DYNARRAY_ELEMENT);
73 DYNARRAY_ELEMENT *DYNARRAY_PREFIX##emplace (struct DYNARRAY_STRUCT *);
74 bool DYNARRAY_PREFIX##resize (struct DYNARRAY_STRUCT *, size_t);
75 void DYNARRAY_PREFIX##remove_last (struct DYNARRAY_STRUCT *);
76 void DYNARRAY_PREFIX##clear (struct DYNARRAY_STRUCT *);
77
78 The following functions are provided are provided if the
79 prerequisites are met:
80
81 bool DYNARRAY_PREFIX##finalize (struct DYNARRAY_STRUCT *,
82 DYNARRAY_FINAL_TYPE *);
83 (if DYNARRAY_FINAL_TYPE is defined)
84 DYNARRAY_ELEMENT *DYNARRAY_PREFIX##finalize (struct DYNARRAY_STRUCT *,
85 size_t *);

20/* To use the dynarray facility, you need to include
21 <malloc/dynarray-skeleton.c> and define the parameter macros
22 documented in that file.
23
24 A minimal example which provides a growing list of integers can be
25 defined like this:
26
27 struct int_array
28 {
29 // Pointer to result array followed by its length,
30 // as required by DYNARRAY_FINAL_TYPE.
31 int *array;
32 size_t length;
33 };
34
35 #define DYNARRAY_STRUCT dynarray_int
36 #define DYNARRAY_ELEMENT int
37 #define DYNARRAY_PREFIX dynarray_int_
38 #define DYNARRAY_FINAL_TYPE struct int_array
39 #include <malloc/dynarray-skeleton.c>
40
41 To create a three-element array with elements 1, 2, 3, use this
42 code:
43
44 struct dynarray_int dyn;
45 dynarray_int_init (&dyn);
46 for (int i = 1; i <= 3; ++i)
47 {
48 int *place = dynarray_int_emplace (&dyn);
49 assert (place != NULL);
50 *place = i;
51 }
52 struct int_array result;
53 bool ok = dynarray_int_finalize (&dyn, &result);
54 assert (ok);
55 assert (result.length == 3);
56 assert (result.array[0] == 1);
57 assert (result.array[1] == 2);
58 assert (result.array[2] == 3);
59 free (result.array);
60
61 If the elements contain resources which must be freed, define
62 DYNARRAY_ELEMENT_FREE appropriately, like this:
63
64 struct str_array
65 {
66 char **array;
67 size_t length;
68 };
69
70 #define DYNARRAY_STRUCT dynarray_str
71 #define DYNARRAY_ELEMENT char *
72 #define DYNARRAY_ELEMENT_FREE(ptr) free (*ptr)
73 #define DYNARRAY_PREFIX dynarray_str_
74 #define DYNARRAY_FINAL_TYPE struct str_array
75 #include <malloc/dynarray-skeleton.c>
76
77 Compared to scratch buffers, dynamic arrays have the following
78 features:
79
80 - They have an element type, and are not just an untyped buffer of
81 bytes.
82
83 - When growing, previously stored elements are preserved. (It is
84 expected that scratch_buffer_grow_preserve and
85 scratch_buffer_set_array_size eventually go away because all
86 current users are moved to dynamic arrays.)
87
88 - Scratch buffers have a more aggressive growth policy because
89 growing them typically means a retry of an operation (across an
90 NSS service module boundary), which is expensive.
91
92 - For the same reason, scratch buffers have a much larger initial
93 stack allocation. */
