SO_NOSIGPIPE was not declared

Question

I am trying to use SO_NOSIGPIPE in a tcp socket.

  int set = 1;
  setsockopt(sockDesc, SOL_SOCKET, SO_NOSIGPIPE, (void *)&set, sizeof(int);

but an error is coming:

   error: SO_NOSIGPIPE was not declared in this scope

Is there any header files required, to use that. I have searched over the Internet but didn't get any useful solution.

Answer 1

There is no SO_NOSIGPIPE in Linux (nor some other systems). You can instead use the MSG_NOSIGNAL flag when calling send(), or use signal(SIGPIPE, SIG_IGN) to make your entire application ignore SIGPIPE.
