+/* Pre-processor macros which act as parameters:
+
+ DYNARRAY_STRUCT
+ The struct tag of dynamic array to be defined.
+ DYNARRAY_ELEMENT
+ The type name of the element type. Elements are copied
+ as if by memcpy, and can change address as the dynamic
+ array grows.
+ DYNARRAY_PREFIX
+ The prefix of the functions which are defined.
+
+ The following parameters are optional:
+
+ DYNARRAY_ELEMENT_FREE
+ DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
+ contents of elements. E is of type DYNARRAY_ELEMENT *.
+ DYNARRAY_ELEMENT_INIT
+ DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
+ element. E is of type DYNARRAY_ELEMENT *.
+ If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
+ defined, new elements are automatically zero-initialized.
+ Otherwise, new elements have undefined contents.
+ DYNARRAY_INITIAL_SIZE
+ The size of the statically allocated array (default:
+ at least 2, more elements if they fit into 128 bytes).
+ Must be a preprocessor constant. If DYNARRAY_INITIAL_SIZE is 0,
+ there is no statically allocated array at, and all non-empty
+ arrays are heap-allocated.
+ DYNARRAY_FINAL_TYPE
+ The name of the type which holds the final array. If not
+ defined, is PREFIX##finalize not provided. DYNARRAY_FINAL_TYPE
+ must be a struct type, with members of type DYNARRAY_ELEMENT and
+ size_t at the start (in this order).
+
+ These macros are undefined after this header file has been
+ included.
+
+ The following types are provided (their members are private to the
+ dynarray implementation):
+
+ struct DYNARRAY_STRUCT
+
+ The following functions are provided:

+/* To use the dynarray facility, you need to include
+ <malloc/dynarray-skeleton.c> and define the parameter macros
+ documented in that file.
+
+ A minimal example which provides a growing list of integers can be
+ defined like this:
+
+ struct int_array
+ {
+ // Pointer to result array followed by its length,
+ // as required by DYNARRAY_FINAL_TYPE.
+ int *array;
+ size_t length;
+ };
+

+ #define DYNARRAY_ELEMENT int
+ #define DYNARRAY_PREFIX dynarray_int_
+ #define DYNARRAY_FINAL_TYPE struct int_array
+ #include <malloc/dynarray-skeleton.c>
+
+ To create a three-element array with elements 1, 2, 3, use this
+ code:
+
+ struct dynarray_int dyn;
+ dynarray_int_init (&dyn);
+ for (int i = 1; i <= 3; ++i)
+ {
+ int *place = dynarray_int_emplace (&dyn);
+ assert (place != NULL);
+ *place = i;
+ }
+ struct int_array result;
+ bool ok = dynarray_int_finalize (&dyn, &result);
+ assert (ok);
+ assert (result.length == 3);
+ assert (result.array[0] == 1);
+ assert (result.array[1] == 2);
+ assert (result.array[2] == 3);
+ free (result.array);
+
+ If the elements contain resources which must be freed, define
+ DYNARRAY_ELEMENT_FREE appropriately, like this:
+
+ struct str_array
+ {
+ char **array;
+ size_t length;
+ };
+
+ #define DYNARRAY_STRUCT dynarray_str

+
+ Compared to scratch buffers, dynamic arrays have the following
+ features:
+
+ - They have an element type, and are not just an untyped buffer of
+ bytes.
+
+ - When growing, previously stored elements are preserved. (It is
+ expected that scratch_buffer_grow_preserve and
+ scratch_buffer_set_array_size eventually go away because all
+ current users are moved to dynamic arrays.)
+
+ - Scratch buffers have a more aggressive growth policy because
+ growing them typically means a retry of an operation (across an
+ NSS service module boundary), which is expensive.
+
+ - For the same reason, scratch buffers have a much larger initial
+ stack allocation. */
