RMDIR(2)                    BSD System Calls Manual                   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.
