At C++, _exit() is a function that terminates the calling process immediately without running any destructors or performing any cleanup. It is defined in the <unistd.h> header file .
Here's an example of how to use _exit() in C++ :
#include <iostream>
#include <unistd.h>
int main() {
std::cout << "Exiting program..." << std::endl;
_exit(0);
}In this example, the _exit() function is called with an exit status code of 0, which indicates successful termination. If you want to indicate an error, you can pass a non-zero exit status code.
It's worth noting that _exit() is a low-level function and should be used with caution . It's generally recommended to use the exit() function instead, which performs some cleanup before terminating the program.
