RMDIR(2)                   Linux Programmer's Manual                  RMDIR(2)



NAME
       rmdir - delete a directory

SYNOPSIS
       #include <unistd.h>

       int rmdir(const char *pathname);

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

RETURN VALUE
       On success, zero is returned.  On error, -1 is returned, and errno is set appropri-
       ately.

ERRORS
       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 permis-
              sion.  (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.

       ENAMETOOLONG
              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.

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

       ENOTEMPTY
              pathname contains entries other than . and .. ; or, pathname has ..  as  its
              final component.  POSIX.1-2001 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 file system containing pathname does not support the removal of directo-
              ries.

       EROFS  pathname refers to a directory on a read-only file system.

CONFORMING TO
       SVr4, 4.3BSD, POSIX.1-2001.

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