| 5038 | 38 A "dynamic array" or "dynarr" is a contiguous array of fixed-size elements |
| 39 where there is no upper limit (except available memory) on the number of | |
| 40 elements in the array. Because the elements are maintained contiguously, | |
| 41 space is used efficiently (no per-element pointers necessary) and random | |
| 42 access to a particular element is in constant time. At any one point, the | |
| 43 block of memory that holds the array has an upper limit; if this limit is | |
| 44 exceeded, the memory is realloc()ed into a new array that is twice as big. | |
| 45 Assuming that the time to grow the array is on the order of the new size of | |
| 46 the array block, this scheme has a provably constant amortized time | |
| 47 \(i.e. average time over all additions). | |
| 428 | 48 |
| 49 When you add elements or retrieve elements, pointers are used. Note that | |
| 50 the element itself (of whatever size it is), and not the pointer to it, | |
| 51 is stored in the array; thus you do not have to allocate any heap memory | |
| 52 on your own. Also, returned pointers are only guaranteed to be valid | |
| 53 until the next operation that changes the length of the array. | |
| 54 | |
| 55 This is a container object. Declare a dynamic array of a specific type | |
| 56 as follows: | |
| 57 | |
| 2367 | 58 typedef struct |
| 59 { | |
| 60 Dynarr_declare (mytype); | |
| 61 } mytype_dynarr; | |
| 428 | 62 |
| 63 Use the following functions/macros: | |
| 64 | |
| 5038 | 65 |
| 66 ************* Dynarr creation ************* | |
| 67 | |
| 428 | 68 void *Dynarr_new(type) |
| 69 [MACRO] Create a new dynamic-array object, with each element of the | |
| 70 specified type. The return value is cast to (type##_dynarr). | |
| 71 This requires following the convention that types are declared in | |
| 72 such a way that this type concatenation works. In particular, TYPE | |
| 5038 | 73 must be a symbol, not an arbitrary C type. To make dynarrs of |
| 74 complex types, a typedef must be declared, e.g. | |
| 75 | |
| 76 typedef unsigned char *unsigned_char_ptr; | |
| 77 | |
| 78 and then you can say | |
| 79 | |
| 80 unsigned_char_ptr_dynarr *dyn = Dynarr_new (unsigned_char_ptr); | |
| 81 | |
| 82 void *Dynarr_new2(dynarr_type, type) | |
| 83 [MACRO] Create a new dynamic-array object, with each element of the | |
| 84 specified type. The array itself is of type DYNARR_TYPE. This makes | |
| 85 it possible to create dynarrs over complex types without the need | |
| 86 to create typedefs, as described above. Use is as follows: | |
| 87 | |
| 88 ucharptr_dynarr *dyn = Dynarr_new2 (ucharptr_dynarr *, unsigned char *); | |
| 89 | |
| 90 Dynarr_free(d) | |
| 91 Destroy a dynamic array and the memory allocated to it. | |
| 92 | |
| 93 ************* Dynarr access ************* | |
| 94 | |
| 95 type Dynarr_at(d, i) | |
| 96 [MACRO] Return the element at the specified index. The index must be | |
| 97 between 0 and Dynarr_largest(d), inclusive. With error-checking | |
| 98 enabled, bounds checking on the index is in the form of asserts() -- | |
| 99 an out-of-bounds index causes an abort. The element itself is | |
| 100 returned, not a pointer to it. | |
| 101 | |
| 102 type *Dynarr_atp(d, i) | |
| 103 [MACRO] Return a pointer to the element at the specified index. | |
| 104 Restrictions and bounds checking on the index is as for Dynarr_at. | |
| 105 The pointer may not be valid after an element is added to or | |
| 106 (conceivably) removed from the array, because this may trigger a | |
| 107 realloc() performed on the underlying dynarr storage, which may | |
| 108 involve moving the entire underlying storage to a new location in | |
| 109 memory. | |
| 110 | |
| 111 type *Dynarr_begin(d) | |
| 112 [MACRO] Return a pointer to the first element in the dynarr. See | |
| 113 Dynarr_atp() for warnings about when the pointer might become invalid. | |
| 114 | |
| 115 type *Dynarr_lastp(d) | |
| 116 [MACRO] Return a pointer to the last element in the dynarr. See | |
| 117 Dynarr_atp() for warnings about when the pointer might become invalid. | |
| 118 | |
| 119 type *Dynarr_past_lastp(d) | |
| 120 [MACRO] Return a pointer to the beginning of the element just past the | |
| 121 last one. WARNING: This may not point to valid memory; however, the | |
| 122 byte directly before will be pointer will be valid memory. This macro | |
| 123 might be useful for various reasons, e.g. as a stopping point in a loop | |
| 124 (although Dynarr_lastp() could be used just as well) or as a place to | |
| 125 start writing elements if Dynarr_length() < Dynarr_largest(). | |
| 126 | |
| 127 ************* Dynarr length/size retrieval and setting ************* | |
| 128 | |
| 129 int Dynarr_length(d) | |
| 130 [MACRO] Return the number of elements currently in a dynamic array. | |
| 131 | |
| 132 int Dynarr_largest(d) | |
| 133 [MACRO] Return the maximum value that Dynarr_length(d) would | |
| 134 ever have returned. This is used esp. in the redisplay code, | |
| 135 which reuses dynarrs for performance reasons. | |
| 136 | |
| 137 int Dynarr_max(d) | |
| 138 [MACRO] Return the maximum number of elements that can fit in the | |
| 139 dynarr before it needs to be resized. | |
| 140 | |
| 141 Note that Dynarr_length(d) <= Dynarr_largest(d) <= Dynarr_max(d). | |
| 142 | |
| 143 Bytecount Dynarr_sizeof(d) | |
| 144 [MACRO] Return the total size of the elements currently in dynarr | |
| 145 D. This | |
| 146 | |
| 147 Dynarr_set_lengthr(d, len) | |
| 148 [MACRO] Set the length of D to LEN, which must be between 0 and | |
| 149 Dynarr_largest(d), inclusive. With error-checking enabled, an | |
| 150 assertion failure will result from trying to set the length | |
| 151 to less than zero or greater than Dynarr_largest(d). The | |
| 152 restriction to Dynarr_largest() is to ensure that | |
| 153 | |
| 154 Dynarr_set_length(d, len) | |
| 155 [MACRO] Set the length of D to LEN, resizing the dynarr as | |
| 156 necessary to make sure enough space is available. there are no | |
| 157 restrictions on LEN other than available memory and that it must | |
| 158 be at least 0. Note that | |
| 159 | |
| 160 Dynarr_set_length_and_zero(d, len) | |
| 161 [MACRO] Like Dynarr_set_length(d, len) but also, if increasing | |
| 162 the length, zero out the memory between the old and new lengths, | |
| 163 i.e. starting just past the previous last element and up through | |
| 164 the new last element. | |
| 165 | |
| 166 Dynarr_incrementr(d) | |
| 167 [MACRO] Increments the length of D by 1. Equivalent to | |
| 168 Dynarr_set_lengthr(d, Dynarr_length(d) + 1). | |
| 169 | |
| 170 Dynarr_increment(d) | |
| 171 [MACRO] Increments the length of D by 1. Equivalent to | |
| 172 Dynarr_set_length(d, Dynarr_length(d) + 1). | |
| 173 | |
| 174 Dynarr_reset(d) | |
| 175 [MACRO] Reset the length of a dynamic array to 0. | |
| 176 | |
| 177 Dynarr_resize(d, maxval) | |
| 178 Resize the internal dynarr storage to so that it can hold at least | |
| 179 MAXVAL elements. Resizing is done using a geometric series | |
| 180 (repeatedly multiply the old maximum by a constant, normally 1.5, | |
| 181 till a large enough size is reached), so this will be efficient | |
| 182 even if resizing larger by one element at a time. This is mostly | |
| 183 an internal function. | |
| 184 | |
| 185 | |
| 186 | |
| 187 ************* Adding/deleting elements to/from a dynarr ************* | |
| 428 | 188 |
| 189 Dynarr_add(d, el) | |
| 190 [MACRO] Add an element to the end of a dynamic array. EL is a pointer | |
| 191 to the element; the element itself is stored in the array, however. | |
| 192 No function call is performed unless the array needs to be resized. | |
| 193 | |
| 194 Dynarr_add_many(d, base, len) | |
| 195 [MACRO] Add LEN elements to the end of the dynamic array. The elements | |
| 771 | 196 should be contiguous in memory, starting at BASE. If BASE if NULL, |
| 197 just make space for the elements; don't actually add them. | |
| 428 | 198 |
| 5038 | 199 Dynarr_prepend_many(d, base, len) |
| 200 [MACRO] Prepend LEN elements to the beginning of the dynamic array. | |
| 428 | 201 The elements should be contiguous in memory, starting at BASE. |
| 771 | 202 If BASE if NULL, just make space for the elements; don't actually |
| 203 add them. | |
| 428 | 204 |
| 5038 | 205 Dynarr_insert_many(d, base, len, pos) |
| 428 | 206 Insert LEN elements to the dynamic array starting at position |
| 5038 | 207 POS. The elements should be contiguous in memory, starting at BASE. |
| 771 | 208 If BASE if NULL, just make space for the elements; don't actually |
| 209 add them. | |
| 210 | |
| 5038 | 211 type Dynarr_pop(d) |
| 212 [MACRO] Pop the last element off the dynarr and return it. | |
| 213 | |
| 771 | 214 Dynarr_delete(d, i) |
| 215 [MACRO] Delete an element from the dynamic array at position I. | |
| 216 | |
| 5038 | 217 Dynarr_delete_many(d, pos, len) |
| 771 | 218 Delete LEN elements from the dynamic array starting at position |
| 5038 | 219 POS. |
| 220 | |
| 221 Dynarr_zero_many(d, pos, len) | |
| 222 Zero out LEN elements in the dynarr D starting at position POS. | |
| 771 | 223 |
| 224 Dynarr_delete_by_pointer(d, p) | |
| 225 [MACRO] Delete an element from the dynamic array at pointer P, | |
| 226 which must point within the block of memory that stores the data. | |
| 227 P should be obtained using Dynarr_atp(). | |
| 428 | 228 |
| 5038 | 229 ************* Dynarr locking ************* |
| 428 | 230 |
| 5038 | 231 Dynarr_lock(d) |
| 232 Lock the dynarr against further locking or writing. With error-checking | |
| 233 enabled, any attempts to write into a locked dynarr or re-lock an | |
| 234 already locked one will cause an assertion failure and abort. | |
| 428 | 235 |
| 5038 | 236 Dynarr_unlock(d) |
| 237 Unlock a locked dynarr, allowing writing into it. | |
| 428 | 238 |
| 5038 | 239 ************* Dynarr global variables ************* |
| 428 | 240 |
| 241 Dynarr_min_size | |
| 440 | 242 Minimum allowable size for a dynamic array when it is resized. |
