rmdir — remove a directory file

The rmdir() system call removes a directory file whose name is given by path. The directory must not have any entries other than ‘.’ and ‘..’.

The named file is removed unless: [ENOTDIR] A component of the path is not a directory. [ENAMETOOLONG] A component of a pathname exceeded 255 characters, or an entire path name exceeded 1023 characters. [ENOENT] The named directory does not exist. [ELOOP] Too many symbolic links were encountered in translating the pathname. [ENOTEMPTY] The named directory contains files other than ‘.’ and ‘..’ in it. [EACCES] Search permission is denied for a component of the path prefix. [EACCES] Write permission is denied on the directory containing the link to be removed. [EPERM] The directory to be removed has its immutable, undeletable or append-only flag set, see the chflags(2) manual page for more information. [EPERM] The parent directory of the directory to be removed has its immutable or append-only flag set. [EPERM] The directory containing the directory to be removed is marked sticky, and neither the containing directory nor the directory to be removed are owned by the effective user ID. [EINVAL] The last component of the path is ‘.’ or ‘..’. [EBUSY] The directory to be removed is the mount point for a mounted file system. [EIO] An I/O error occurred while deleting the directory entry or deallocating the inode. [EINTEGRITY] Corrupted data was detected while reading from the file system. [EROFS] The directory entry to be removed resides on a read-only file system. [EFAULT] The path argument points outside the process's allocated address space.
