Change History (most recent first): |
2.0 08/13/2008 Add Leopard user client API for supporting 64-bit user processes. |
Now requires Xcode 3.0 or later to build. |
1.1 05/22/2007 Perform endian swapping when called from a user process running |
under Rosetta. Updated to produce a universal binary. Now requires |
Xcode 2.2.1 or later to build. |
1.0d3 01/14/2003 New sample. |
