What you'd have to do, if you chose to use diffutils stuff, is to transform the main() of diff in diff_main(), use setjmp/longjmp to capture its exit()s, and make it use a proper allocator (if you want to avoid leaks upon aborts). You can see an example inside the diff/libgdiff directory of this packages: https://www.cvshome.org http://www.opencm.org In that way, instead of executing "diff -u ...", you'd call diff_main() with the proper args array. The CVS one (the other project seems dead, and they lifted the thing from CVS anyway) should be readily usable. - Davide - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.htmlReceived on Mon Sep 26 02:08:07 2005
