iostream buffer flushing and unitbuf

[Ian S. Worthington]

Hi --

We're using the gnu iostream library under z/tpf. 

Multiline output messages to cout are being prefixed with a z/tpf header in
such a way as to make us suspect that each \n is generating a flush.

I have tried setting nounitbuf without effect.

When I look through the iostream code I find a number of places which set the
unitbuf flag but very few places which actually interrogate it.

Could someone point me to where this flag is being used to control buffer
flushing?

Thanks,


ian
