Broken pipe when socket is closed

Question

I have a server/client app on a Linux box. If the server is not up when the client attempts to send a request, I get a SIGPIPE and the application terminates.

How can I check if the server is available on the socket before I try to write?

Also of note, I do not want to trap the SIGPIPE because the client is really part of a shared object that is used by many applications that may or may not already define their own signal handling methods.

Thanks

Pass MSG_NOSIGNAL as flags to send()
