AFAIK, dlopen() requires cgo simply due to the fact it's not just a thin wrapper around some syscall (like, say, open() is) but it's actually implemented in libc. So I think what you can do is to start with [1] and chase the code paths from there. Note that surely other libc implementations exist, such as muzzle and ulibc, and they could have simpler implementations. (Maybe, I'm not sure.) 1. https://github.com/lattera/glibc/blob/master/dlfcn/dlopen.c -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
