Just out of curiosity: libstdubf.c defines fileno_to_name, apply_mode, and stdbuf for LD_PRELOAD-ing, but AFAICT these aren't defined in glibc; where are they called from?
Notice the __attribute__ ((constructor)) on libstdbuf::stdbuf(). That means that function will be called before main() on any program that preloads it. The lib is not meant to be used directly really, and instead the stdbuf program sets things up appropriately. cheers, Pádraig.
