title: dlopen() search path
body: <p>is there a way to find out programmatically which paths are searched by dlopen() for shared objects? I always thought dlopen() would only look in /lib and /usr/lib but now I've seen that on Linux Mint several core components like libglib-2.0.so are in a wholly different folders, namely in /rofs/lib/i386-gnu-linux and some others. Is there a way to get to know all these paths that dlopen() will search through for a shared object? I already checked the environment variable LD_LIBRARY_PATH but it's not defined at all.</p>
