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 appropriately.

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   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.

       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 directories.

       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.
