- * get_symbol

- * Here it gets ugly :-(
- * This is quick hack to get the address of first_dll in a running process
- * We make the following assumptions:
- * - libwine (lib) is loaded in all processes at the same address (or
- * at least at the same address at this process)
- * - we load the same libwine.so version in this process and in the
- * examined process
- * Final address is gotten by: 1/ querying the address of a known exported
- * symbol out of libwine.so with dlsym, 2/ then querying nm on libwine.so to
- * get the offset from the data segment of this known symbol and of first_dll,
- * 3/ computing the actual address of first_dll by adding the result of 1/ and
- * the delta of 2/.
- * Ugly, yes, but it somehow works. We should replace that with debughlp
- * library, that'd be way better. Exporting first_dll from libwine.so would make
- * this code simpler, but still ugly.
