file dir 结构体

1.存储目录中的文件信息(文件名、扩展名等等)

#include <dirent.h>
struct dirent
{
long d_ino;   /* inode number 索引节点号 */
off_t d_off;   /* offset to this dirent 在目录文件中的偏移 */
unsigned short d_reclen;  /* length of this d_name 文件名长 */
unsigned char d_type; /* the type of d_name 文件类型 */
char d_name [NAME_MAX+1]; /* file name (null-terminated) 文件名,最长255字符 */
}

  

2.

 

struct __dirstream
{
void *__fd; /* `struct hurd_fd' pointer for descriptor. */
char *__data; /* Directory block. */
int __entry_data; /* Entry number `__data' corresponds to. */
char *__ptr; /* Current pointer into the block. */
int __entry_ptr; /* Entry number `__ptr' corresponds to. */
size_t __allocation; /* Space allocated for the block. */
size_t __size; /* Total valid data in the block. */
__libc_lock_define (, __lock) /* Mutex lock for this structure. */
};
typedef struct __dirstream DIR;
