I see that send()/write() can generate SIGPIPE

  checking for the EPIPE error? Are there any useful parameters passed
  to the signal catching function?

  From Andrew Gierth (andrew@erlenstar.demon.co.uk):

  In general, the only parameter passed to a signal handler is the
  signal number that caused it to be invoked.  Some systems have
  optional additional parameters, but they are no use to you in this

  My advice is to just ignore SIGPIPE as you suggest. That's what I do
  in just about all of my socket code; errno values are easier to handle
  than signals (in fact, the first revision of the FAQ failed to mention
  SIGPIPE in that context; I'd got so used to ignoring it...)

  There is one situation where you should not ignore SIGPIPE; if you are
  going to exec() another program with stdout redirected to a socket. In
  this case it is probably wise to set SIGPIPE to SIG_DFL before doing
  the exec().
