Re: connect() not interrupted by sigalrm?

[Eric Mandel <eric at head-cfa dot harvard dot edu>]

Dear Corinna,

Thanks for the quick clarification on plans for interruptible connect().

Cf. Stevens "Unix Network Programming", section 15.3:

    "There are many portability problems with nonblocking connnects
    that we mention in the examples that follow."

and, after a lengthy discussion of portability issues:

     "Unfortunately, nonblocking connects are one of the most nonportable
     areas of network programming."

Since my code must run on several flavors of Unix, I hesitate to use
this technique. I suppose I could use it solely for Cygwin and retain
the more portable alarm()/connect() technique for the other platforms,
and that is what I am considering now.

Regards,

Eric
