In Linux it's the case for all searched-for objects, as far as I know - anything found via search paths, LD_LIBRARY_PATH, DT_RUNPATH, DT_RPATH, etc. will either be an absolute path or else contain slashes and be relative to the current directory. If it's not true for dlopen'd objects, well, there's no way to know where the app had chdir'd to when it loaded them. Do you know offhand when it's not true for GNU/Linux? -- Daniel Jacobowitz MontaVista Software Debian GNU/Linux Developer
