Node.js process.exit() will not exit with a createReadStream open

问题 I have a program that communicates with Asterisk via EAGI. Asterisk opens up my Node.js application and sends it data via STDIN and the program sends Asterisk commands via STDOUT. When a user hangs up, the Node.js process gets sent a SIGHUP command. This is intercepted for cleaner exiting. This functionality is working. Asterisk also sends RAW audio data on fd 3 (STDERR+1). The Node.js process intercepts the data properly, and is able to read the audio, convert it, or anything else that needs

问题 I need to use defer to free allocations manually created using C library, but I also need to os.Exit with non 0 status at some point. The tricky part is that os.Exit skips any deferred instruction: package main import "fmt" import "os" func main() { // `defer`s will _not_ be run when using `os.Exit`, so // this `fmt.Println` will never be called. defer fmt.Println("!") // sometimes ones might use defer to do critical operations // like close a database, remove a lock or free memory // Exit

问题 I am learning x86 assembly. I am trying to understand how "exiting program" works on x86. We have a code : push ebp mov ebp,esp //Some stuff here mov esp, ebp pop ebp ret When processor executes instruction "ret" : EIP will have value, which is popped from stack, in other words 0. so processor will go to 0 address and will try to execute instructions ... which doesn't contain program code/executable code. So, what is really going on with processor? Are there condition check, for example, if

How to disable exit button: #region items to disable quit-button const int MF_BYPOSITION = 0x400; [DllImport("User32")] private static extern int RemoveMenu

问题 I am currently using Python3 in Jupyter Notebook and I just ran into a keyword exit . What does this keyword do ? with open("some_file.txt") as f: for lines in f: print(lines) exit 回答1: The exit lines in your loop do nothing. Why they do nothing is a bit more complicated than the usual reason exit would do nothing in Python, though. Normally, exit on a line by its own wouldn't exit Python. At most, in interactive mode, it would print a message telling you how to quit Python (message
