C++ Program to Handle SIGABRT Signal in C++
The following program demonstrates how we can handle a SIGABRT signal in C++ using the signal function:
// C++ Program to Handle SIGABRT Signal in C++
#include <csignal>
#include <cstdlib>
#include <iostream>
using namespace std;
// Signal handler function for SIGABRT
void handleSigabrt(int signal)
{
cerr
<< "SIGABRT received. Terminating the Program...\n";
// Perform any cleanup tasks here
// optionally holding the program
int i;
cin >> i;
}
int main()
{
// Set up the signal handler for SIGABRT
signal(SIGABRT, handleSigabrt);
// Inform the user that the program is running
cout << "Program running. Send SIGABRT signal to "
"terminate.\n";
// send the SIGABRT signal by calling the abort function
abort();
// The below code will not be executed
cout << "This line will not be printed";
return 0;
}
Output
Program running. Send SIGABRT signal to terminate.
SIGABRT received. Terminating the Program...
Time Complexity: O(1), as the signal function takes constant time.
Auxiliary Space: O(1), as no extra space is used.
Explanation: In the above program, we have manually sent a SIGABRT signal by calling the abort() function to demonstrate how a SIGABRT signal can be handled. As the compilers or systems usually send the SIGABRT signal, it was impossible to illustrate a situation where an actual SIGABRT signal is received.
How to Handle SIGABRT Signal in C++
In C++, SIGABRT short for Signal Abort is a signal used by the abort function to indicate an abnormal program termination. This is commonly used to signal critical errors where continuing the execution of the program is not possible. In this article, we will learn how to handle SIGABRT Signal in C++.
