This is ususally called name mangling. You should find lots of information on this in the net. Look also for linkage, extern "C" to get the whole picture. C++ allows overloading, i.e. functions with the same function name, but different argument lists. The only way to map this onto the existing linker structure (which comes from C, which does not allow overloading) is coding the argument list and more into the actual name the function is known to the linker. So overloaded functions have unique names again. Since overloading could happen in different compilation units, i.e. the compiler cannot decide whether mangling is unnecessary, mangling is done by default, for all functions. There is a small app called c++filt, which takes some text as input and translates mangled names into readable names. Many applications like objdump or nm dealing with object files and other binaries have the ability to translate mangled names to readable output by some option. See the manuals. Try cat Test.s | c++filt | less Bernd Strieder _______________________________________________ help-gplusplus mailing list help-gplusplus@gnu.org http://lists.gnu.org/mailman/listinfo/help-gplusplus
