65 | * The dirent structure defines the format of directory entries. |
66 | * |
67 | * A directory entry has a struct dirent at the front of it, containing its |
68 | * inode number, the length of the entry, and the length of the name |
69 | * contained in the entry. These are followed by the name padded to a 4 |
70 | * byte boundary with null bytes. All names are guaranteed null terminated. |
71 | * The maximum length of a name in a directory is MAXNAMLEN when 32-bit |
72 | * ino_t is in effect; (MAXPATHLEN - 1) when 64-bit ino_t is in effect. |
