RMDIR(2)

NAME
rmdir - remove a directory file

SYNOPSIS
#include <unistd.h>
int
rmdir(const char *path);

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

RETURN VALUES
A 0 is returned if the remove succeeds; otherwise a -1 is returned and an error code is stored in the global location errno.

ERRORS
The named file is removed unless:

[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.

[EBUSY]
    The directory to be removed is the mount point for a mounted file system.

[EFAULT]
    Path points outside the process's allocated address space.

[EIO]
    An I/O error occurs while deleting the directory entry or deallocating the inode.

[ELOOP]
    Too many symbolic links are encountered in translating the pathname. This is taken to be indicative of a looping symbolic link.

[ENAMETOOLONG]
    A component of a pathname (possibly expanded by a symbolic link) exceeds {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters.

[ENOENT]
    The named directory does not exist.

[ENOTDIR]
    A component of the path is not a directory.

[ENOTEMPTY]
    The named directory contains files other than ‘’. and ‘..’ in it.

[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.

[EROFS]
    The directory entry to be removed resides on a read-only file system.
