报错：warning: format ‘***’ expects argument of type ‘int’, but argument 2 has type ‘size_t’ [-Wformat]

print("strlen(dirp->d_name) : %d \n", strlen(dirp->d_name));

报了 下面的错误

warning: format ‘%d’ expects argument of type ‘int’, but argument 2 has type ‘size_t’ [-Wformat]

怎么改？

把%d更换为%zu就可以了。

%zu用来输出size_t 类型

pri("strlen(dirp->d_name) : %zu \n", strlen(dirp->d_name));
