If all architectures would finally get a vdso implementation you could just add the necessary stub in the vdso, add a symbol in the symbol table of the vdso, and use in the userlevel code sym = dlsym (RTLD_DEFAULT, "the_symbol_name") If the returned value is not NULL the symbol exists. I've described this many times as one of the huge advantages of vdsos, hopefully this time it clicks. -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
