-# _emx_link.py
-
-# Written by Andrew I MacIntyre, December 2002.
-
-"""_emx_link.py is a simplistic emulation of the Unix link(2) library routine
-for creating so-called hard links.  It is intended to be imported into
-the os module in place of the unimplemented (on OS/2) Posix link()
-function (os.link()).
-
-We do this on OS/2 by implementing a file copy, with link(2) semantics:-
-  - the target cannot already exist;
-  - we hope that the actual file open (if successful) is actually
-    atomic...
-
-Limitations of this approach/implementation include:-
-  - no support for correct link counts (EMX stat(target).st_nlink
-    is always 1);
-  - thread safety undefined;
-  - default file permissions (r+w) used, can't be over-ridden;
-  - implemented in Python so comparatively slow, especially for large
-    source files;
-  - need sufficient free disk space to store the copy.
-
-Behaviour:-
-  - any exception should propagate to the caller;
-  - want target to be an exact copy of the source, so use binary mode;
-  - returns None, same as os.link() which is implemented in posixmodule.c;
-  - target removed in the event of a failure where possible;
-  - given the motivation to write this emulation came from trying to
-    support a Unix resource lock implementation, where minimal overhead
-    during creation of the target is desirable and the files are small,
-    we read a source block before attempting to create the target so that
-    we're ready to immediately write some data into it.
