我的delete_table函数有问题。所以我有两个结构
struct _entry_ {
int key;
int data;
struct _entry_* next;
struct _entry_* prev;
};
typedef struct _entry_ entry;
struct _table_ {
entry** entries;
int size;
};
typedef struct _table_ table;
我使用calloc初始化我的表。
void table_init(table* ht, int initial_size) {
ht->entries = (entry**)calloc(initial_size, sizeof(entry*));
if (ht->entries) {
ht->size = initial_size;
}
}
现在我写的自由函数
void table_destroy(htable* ht) {
entry *el, *temp;
int i;
for(i = 0; i < ht->size; i++) {
el = ht->entries[i];
while(el != NULL){
temp = el;
el = el->next;
free(temp);
}
free(ht->entries[i]);
}
free(ht); // <- don't know do i need this.
}
当我用valgrind测试它时出现了这个错误
==13560== Invalid free() / delete / delete[] / realloc()
==13560== at 0x4C2BDEC: free (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)
==13560== by 0x400783: htable_destroy (htable.c:46)

==13560== Address 0xffefffae0 is on thread 1's stack

任何帮助都会很棒,谢谢你的时间!
