       rmdir - delete a directory


       #include <unistd.h>

       int rmdir(const char *pathname);


       rmdir() deletes a directory, which must be empty.


       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.


       EACCES Write  access  to  the directory containing pathname was not allowed, or one of the
              directories in the path prefix of pathname did not allow search  permission.   (See
              also path_resolution(7).

       EBUSY  pathname  is  currently  in  use  by  the  system or some process that prevents its
              removal.  On Linux this means pathname is currently used as a mount point or is the
              root directory of the calling process.

       EFAULT pathname points outside your accessible address space.

       EINVAL pathname has .  as last component.

       ELOOP  Too many symbolic links were encountered in resolving pathname.

              pathname was too long.

       ENOENT A directory component in pathname does not exist or is a dangling symbolic link.

       ENOMEM Insufficient kernel memory was available.

              pathname,  or  a  component  used  as  a  directory in pathname, is not, in fact, a

              pathname contains entries other than . and .. ; or, pathname has ..  as  its  final
              component.  POSIX.1 also allows EEXIST for this condition.

       EPERM  The  directory  containing  pathname  has  the  sticky  bit  (S_ISVTX)  set and the
              process's effective user ID is neither the user ID of the file to  be  deleted  nor
              that of the directory containing it, and the process is not privileged (Linux: does
              not have the CAP_FOWNER capability).

       EPERM  The filesystem containing pathname does not support the removal of directories.

       EROFS  pathname refers to a directory on a read-only filesystem.


       POSIX.1-2001, POSIX.1-2008, SVr4, 4.3BSD.


       Infelicities in the protocol underlying NFS can  cause  the  unexpected  disappearance  of
       directories which are still being used.
