Is there a way to diff files from C++?
I'm looking for a C or C++ diff library. I know I can use the Unix diff tool in combination with system or exec, but I really want a library. It would be handy if the library could perform patches as well, like the Unix patch tool.

I think I've found a good solution, finally:
The DTL - Diff Template Library --- Tutorial
It supports patch. I had to type "diff.cpp" into Google to find it. Hopefully it works!
