* SYNOPSIS
* darray_init(foo.a);
* darray_free(foo.a);
*
- * const struct {
- * darray(int) a;
- * } foo = {
- * .a = darray_lit({1, 2, 3})
- * };
- *
* Typedefs for darrays of common types:
*
* darray_char, darray_schar, darray_uchar
* void darray_appends(darray(T) arr, [T item, [...]]);
* void darray_prepends(darray(T) arr, [T item, [...]]);
*
- * // Same functionality as above, but does not require typeof.
- * void darray_appends_t(darray(T) arr, #T, [T item, [...]]);
- * void darray_prepends_t(darray(T) arr, #T, [T item, [...]]);
- *
* Removal:
*
* T darray_pop(darray(T) arr | darray_size(arr) != 0);
* void darray_realloc(darray(T) arr, size_t newAlloc);
* void darray_growalloc(darray(T) arr, size_t newAlloc);
*
- * void darray_make_room(darray(T) arr, size_t room);
- *
* Traversal:
*
* darray_foreach(T *&i, darray(T) arr) {...}
