| * Registry, but @dll_name is non-%NULL, it should name a DLL loaded |
| * into the current process. Typically that would be the name of the |
| * DLL calling this function, looking for its installation |
| * directory. The function then asks Windows what directory that DLL |
| * was loaded from. If that directory's last component is "bin" or |
| * "lib", the parent directory is returned, otherwise the directory |
| * itself. If that DLL isn't loaded, the function proceeds as if |
| * @dll_name was %NULL. |
| * |
| * If both @package and @dll_name are %NULL, the directory from where |
| * the main executable of the process was loaded is uses instead in |
| * the same way as above. |
| * |
| * Returns: a string containing the installation directory for @package. |
| * The return value should be freed with g_free() when not needed any longer. |
