Re: select() doesn't respect SO_RCVLOWAT ?

Dear Alan,

I am positive. I can setsockopt, and then, getsockopt returns the value
that I requested.

Stevens very clearly states that SO_RCVLOWAT has a direct impact on
select() and I assumed that this would be the case for Linux.
What is the rationale for not complying with that ? Is it the micromanagement
of select() that you dislike ? Isn't a significant reduction in the
amount of read operations a real gain in high speed networking ?

Best Regards,
Felix
