signal(registered signal, signal handler) 1. 这个函数接收两个参数:第一个参数是一个整数,代表了信号的编号;第二个参数是一个指向信号处理函数的指针。 让我们编写一个简单的 C++ 程序,使用 signal() 函数捕获 SIGINT 信号。不管您想在程序中捕获什么信号,您都必须使用signal函数来注册信号,并将其与信号处理程...

Can you return a non-zero exit code when SIGINT is passed in? I don't think it's normal for a program to return 0 when ctrl+c is pressed. I don't know the SIGBREAK signal, but perhaps the same applies there as well. https://github.com/conan-io/conan/blob/develop/conans/client...
It seems like CTRL-C or SIGINT only kills the statements on the client end, and the statements continue to execute server side. How does the KILL command affect a stored procedure that is mid-transaction? Does it trigger the DECLARE HANDLER? If so, with what SQLSTATE? Thank you!Navig...

process.on('SIGINT', function () { process.exit(somecode); // now the "exit" event will fire }); Just because the built-in handler won't do it for me. It also means I can no longer depend on the default exit code that Node associates with SIGINT, which apparently is 128 + sign...
