Well, it's complicated, and I hesitate to even suggest this, but when
you use gdb it knows the names of the shared libraries that the
program uses.  It does this by using hooks provided by the dynamic
linker.  I can't remember the details, and I can't remember whether it
is possible to use those hooks from inside the program.

dynamic linker.
