是否有glibc附带的自动调整大小/动态数组实现？

Question

在glibc或C的任何标准Linux库中是否有动态数组实现？我希望能够添加到列表而不必担心它的大小.我知道std :: vector存在于C++中,但我需要C等价物.

Answer 1

我猜你在想realloc.但最好将结构中的列表包装起来以跟踪其当前长度

示例API

struct s_dynamic_array {
    int allocated;   /* keep track of allocated size  */
    int usedLength;  /* keep track of usage           */
    int *array;      /* dynamicaly grown with realloc */
};
typedef struct s_dynamic_array s_dynamic_array;

s_dynamic_array *new_dynamic_array(int initalSize);
void             free_dynamic_array(s_dynamic_array *array);
int              size_of_dynamic_array(s_dynamic_array *array);
s_dynamic_array *add_int_to_dynamic_array(s_dynamic_array *array, int value);
int              int_at_index(s_dynamic_array *array, int index);
