NAME

     rmdir -- remove a directory file

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <unistd.h>

     int
     rmdir(const char *path);

DESCRIPTION

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

RETURN VALUES

     The rmdir() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.

ERRORS

     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.

     [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.
