On Mac OS X you can use vmmap $pid to get a list of mapped memory regions for a process. This does show all loaded libraries (at least it works for me here on 10.7.5).

ps -A will give you a list of all processes, so ps -A | grep $APPNAME will get you your process id $pid for use with vmmap $pid. lsof -p $pid also works.

The question seems to be asking for a dynamic method from C++. You could poll with these commands and analyse the results, although you may miss fast load/unload events.

lsof is open source software under a BSD licence. Its source code no doubt provides some insight for how to do this from C/C++. See: http://en.wikipedia.org/wiki/Lsof
