41 * The dirent structure defines the format of directory entries returned by
42 * the getdirentries(2) system call.
44 * A directory entry has a struct dirent at the front of it, containing its
45 * inode number, the length of the entry, and the length of the name
46 * contained in the entry. These are followed by the name padded to a 4
47 * byte boundary with null bytes. All names are guaranteed null terminated.
48 * The maximum length of a name in a directory is MAXNAMLEN.
52 __uint32_t d_fileno; /* file number of entry */
53 __uint16_t d_reclen; /* length of this record */

55 __uint8_t d_namlen; /* length of string in d_name */

96 * The _GENERIC_DIRSIZ macro gives the minimum record length which will hold
97 * the directory entry. This requires the amount of space in struct direct
98 * without the d_name field, plus enough space for the name with a terminating
99 * null byte (dp->d_namlen+1), rounded up to a 4 byte boundary.
101 * XXX although this macro is in the implementation namespace, it requires
102 * a manifest constant that is not.
