I actually did write that. And it actually did work. Oh whoa, RFC 3779 talks about that - it’s an “abbreviated prefix”. So 127.1 should work? $ ping

IFunc, #[deku(id_pat = "_")] Other(u8), } Whoa, whoahey, that’s a lot of code, isn’t it? Yeah, but it’s not that bad, is it? We’re just making some nice abstractions, as usual, and using what deku gives us to parse symbols easily. Now that we have all that, we can focus on actually applying relocations. And, remember how we very

main(void) { // was "main" void *lib = dlopen("./libmain.so", RTLD_LAZY); // etc. } $ gcc -Wall load.c -o load -ldl $ ./load Hello, venus! Whoa, that’s neat! Can we take a look at LD_DEBUG output for this run? Sure, let’s g- …but this time, can we filter it out a little, so it fits in one or two screens? Okay, sure. When LD_DEBUG
