[Rd] writeBin and short writes

[irederik m@iii@g oii oib@@et]

Dear R-devel,

I'm curious why writeBin should always return NULL. Would anyone's code break if we made it return the number of bytes written? I'm not sure how else I'm supposed to use writeBin on a writable connection in non-blocking mode...

See attached.

Thank you,

Frederick
