It has an * internal buffer that is pre-allocated with a greater capacity than necessary * in order to foresee new elements being added. The items can be added at both * ends of the list and at the middle (with a given index). * * Insertions at the start are more costly as it is necessary to shift all * elements one position to the right to give space to a new element being added * at index 0. Insertions at the end are instantaneous as long as there is * enough space in the buffer. Insertions at the middle will be based on an * index. The index represents where the element being added will be located * once the operation ends. This operation might also need to shift elements. It * is also possible to add arrays of elements in the list. * * When the buffer is filled, it is reallocated with a greater capacity, usually * being doubled. * * Removing elements follows the same principle. Removing the front element will * require to shift all other elements one position to the left, thus being * slower than removing from the end in which is done in constant time. Removing * elements in the middle of the list will also require shifting elements to the * left. Is is also possible to remove a range of elements or extract them, * creating a new list with the removed items. * * The iterator is a simple structure that is capable of going back and * forwards. Any modifications to the target list during iteration is considered * undefined behavior. Its sole purpose is to facilitate navigation through a * list. */ #include "cor/core.h" #ifdef CMC_DEV #include "utl/log.h" #endif #if defined(CMC_SAC) && !defined(SIZE) #error "When using CMC_SAC, please also define SIZE" #endif /** * Used values * V - list data type * SNAME - struct name and prefix of other related structs * PFX - functions prefix */ /* Structs definition */ #include "cmc/list/struct.h" /* Function declaration */ #include "cmc/list/header.h" /* Function implementation */ #include "cmc/list/code.h" /** * Extensions * * INIT - Initializes the struct on the stack * ITER - List iterator * SEQ - Push and pop sequence of items * STR - Print helper functions */ #define CMC_EXT_LIST_PARTS INIT, ITER, SEQ, STR /**/ #include "cmc/list/ext/struct.h" /**/ #include "cmc/list/ext/header.h" /**/ #include "cmc/list/ext/code.h" #include "cor/undef.h"
