我在调试器中设置了这些变量:
//调试器值不是代码
relative_path =" ./ bin / Debug"
strlen的(RELATIVE_PATH)= 11
relative_path [11] = 0' \ 000' //如Eclipse调试器中所示
在我的代码中,我会这样做:
//**My Code**
struct dirs_later {
const char *findme;
struct dirent *dptr;
struct stat this_lstat;
char *relative_path;
const char *type_str;
DIR * dir;
};
....
struct dirs_later *new_dir = malloc(sizeof(struct dirs_later*));
...
char *relative_path2 = strdup(relative_path);
if (NULL != new_dir) {
new_dir->findme = findme;
new_dir->dptr = dptr;
new_dir->this_lstat = *this_lstat;
new_dir->relative_path = relative_path2;
new_dir->type_str = type_str;
}
但是调试器显示在new_dir-> relative_path = relative_path2之后。然后在调试器中:
//调试器值不是代码
relative_path2 ="& \ 275 \ 001"和
strlen(relative_path2)= 3
我也在我的代码中试过这个:
//**My Code**
char *relative_path2 = malloc(strlen(relative_path) + 1 * sizeof(char));
//check for NULL
strcpy(relative_path2, relative_path);
我得到了相同的结果
答案 0 :(得分:2)
该行
struct dirs_later *new_dir = malloc(sizeof(struct dirs_later*));
是
struct dirs_later *new_dir = malloc(sizeof(struct dirs_later));
因为你想在堆上为结构创建空间,而不仅仅是指针。
