Detailed Description

Exception class for lost or failed backend connection.

Warning

When this happens on Unix-like systems, you may also get a SIGPIPE signal. That signal aborts the program by default, so if you wish to be able to continue after a connection breaks, be sure to disarm this signal.

If you're working on a Unix-like system, see the manual page for signal (2) on how to deal with SIGPIPE. The easiest way to make this signal harmless is to make your program ignore it:

#include <signal.h>
 
int main()
{
  signal(SIGPIPE, SIG_IGN);
  // ...
