NAME
     link - make a hard link to a file

SYNOPSIS
     link(name1, name2)
     char *name1, *name2;

DESCRIPTION
     A	hard  link to name1 is created; the link has the name name2.  Name1 must
     exist.

     With hard links, both name1 and name2 must be in the same file system.  Un-
     less the caller is the super-user, name1 must not be a directory.	Both the
     old and the new link share equal access and rights to  the  underlying  ob-
     ject.

RETURN VALUE
     Upon  successful  completion, a value of 0 is returned.  Otherwise, a value
     of -1 is returned and errno is set to indicate the error.

ERRORS
     Link will fail and no link will be created if one or more of the  following
     are true:

     [ENOTDIR]	    A component of either path prefix is not a directory.

     [EINVAL]	    Either pathname contains a character with the high-order bit
		    set.

     [ENAMETOOLONG]
		    A  component  of either pathname exceeded 255 characters, or
		    entire length of either path name exceeded 1023 characters.

     [ENOENT]	    A component of either path prefix does not exist.

     [EACCES]	    A component of either path prefix denies search permission.

     [EACCES]	    The requested link requires writing in a  directory  with  a
		    mode that denies write permission.

     [ELOOP]	    Too  many symbolic links were encountered in translating one
		    of the pathnames.

     [ENOENT]	    The file named by name1 does not exist.

     [EEXIST]	    The link named by name2 does exist.

     [EPERM]	    The file named by name1 is a  directory  and  the  effective
		    user ID is not super-user.

     [EXDEV]	    The  link  named by name2 and the file named by name1 are on
		    different file systems.

     [ENOSPC]	    The directory in which the entry for the new link  is  being
		    placed  cannot be extended because there is no space left on
		    the file system containing the directory.

     [EDQUOT]	    The directory in which the entry for the new link  is  being
		    placed  cannot  be extended because the user's quota of disk
		    blocks on the file system containing the directory has  been
		    exhausted.

     [EIO]	    An	I/O  error occurred while reading from or writing to the
		    file system to make the directory entry.

     [EROFS]	    The requested link requires writing  in  a	directory  on  a
		    read-only file system.

     [EFAULT]	    One  of the pathnames specified is outside the process's al-
		    located address space.
