RMDIR(2)                    BSD System Calls Manual                   RMDIR(2)

NAME
     rmdir -- remove a directory file

SYNOPSIS
     #include <&lt;unistd.h>&gt;

     int
     rmdir(const char *path);

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

     There is no rmdirat() function; to remove a directory with a path rela-
     tive to the directory associated with a file descriptor use the
     unlinkat(2) function with the AT_REMOVEDIR flag.

RETURN VALUES
     Upon successful completion, the value 0 is returned; 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 NAME_MAX charac-
                        ters, or an entire pathname (including the terminating
                        NUL) exceeded PATH_MAX bytes.

     [ENOENT]           The named directory does not exist.

     [ELOOP]            Too many symbolic links were encountered in translat-
                        ing 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 directory to be removed.

     [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.

     [EPERM]            The directory to be removed or the directory contain-
                        ing it has its immutable or append-only flag set (see
                        chflags(2)).

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

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