Hello, guys!

I use some XS library, that writes to stderr itself log by the libc fprintf() function. In perl script I wanna catch all stderr, produced by this library, but I couldn't, due to stdio makes output buffered.

Code like: 

  select(STDERR);
  $| = 1;

did not help, because XS and perl code have the same file descriptor (2), but the different bound stdio buffers.

The only thing, that helped me, is flushing of all open output streams: 

use Inline C => <<'END_C';
void make_flush() {
    fflush(NULL);
}
END_C

Please, can anyone help me to make this flush without using of C inlined code?
