It makes no difference whether you call fputs() from XS code or via a wrapper of an external library function - fputs() lives in the stdio implementation and does the same for both XS and library code.

And since stdio has its own ideas about buffering, I guess the safest thing to do is calling fflush() as you did. All that with much handwaving, since I'm not proficient with C.

I remember having read remarks and caveats wrt to stdio, and advice to use the PerlIO layer instead. Sorry for being too lazy to delve into docs/sources to bring up those bits... maybe another monk has them present? - thanks ;)
