Question

I am using a dev system where I have to specify the lib name when accessing a function inside it.

I’ve used functions like open() before, and somehow found out that they’re in libc.so.

Now I want to use lstat(), but it appears that this one is not in libc. Sadly, the man pages I looked at do not document the location of the functions.

So, two questions:

1. Can someone tell which lib hosts lstat?
2. How can I generally find this out? Other than using grep “name” on all files in the lib folder, I mean.

Answer 1

Build a simple testcase in C, compile it and run ‘ldd -r’ on it to check what libs are loaded. If you don’t get lstat() in C then you have a problem on your dev env. Or this env dates back before the age of symlinks 🙂
