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.

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