c-post_menu分段故障(核心转储)

Question

我刚开始用Ncurses编程，但当我启动这个程序时，我得到了"Segmentation fault（core dump）"。当我调用函数post_menu（…）时会发生这种情况。

char *mainMenu_choices[] = {
           "Say Hello!",
           "Close", 
           };
ITEM **mainMenu_items = (ITEM **)NULL;
MENU *mainMenu = (MENU *)NULL;
int mainMenu_choices_COUNT, i = 0;
int mainMenu_status = TRUE;
ITEM *mainMenu_selectedItem = (ITEM *)NULL;
int draw_mainMenu()
{
     mainMenu_status = TRUE;
     mainMenu_choices_COUNT = ARRAY_SIZE(mainMenu_choices);
     mainMenu_items = (ITEM **)calloc(mainMenu_choices_COUNT + 1, sizeof(ITEM *));
     for(i = 0; i < mainMenu_choices_COUNT; i = i + 1)
     {                              
          mainMenu_items = new_item(mainMenu_choices[i], mainMenu_choices[i]);
     }
     mainMenu_items[mainMenu_choices_COUNT] = (ITEM *)NULL;     
     mainMenu = new_menu((ITEM **)mainMenu_items);
     post_menu(mainMenu);
     refresh();
     return 0;
}

提前谢谢。附言：很抱歉我没有发表评论。

Answer 1

您没有在循环中正确填充mainMenu_items。

你在做

mainMenu_items = ...

但你可能是指

mainMenu_items[i] = ...
