Handling SIGABRT Signal in C++
In C++, the SIGABRT signal is sent to a process when an unrecoverable error occurs, usually due to assertion failure or a call to the abort() function. By default, when a process receives SIGABRT, it prints a message on the console and terminates the program abnormally. However, we can set up custom signal handlers to catch SIGABRT and perform custom actions such as logging required information or cleanup processes before termination of the program.
To handle the SIGABRT signal in C++, we must register a signal handler function using the signal() function provided by the <csignal> header. Following is the syntax to use signal() function in C++:
Syntax
signal(int signum, signal_Handler);
where:
- signum: specifies the signal number for which the action is being set for example SIGABRT.
- signal_Handler: name of the signal handler function that will be called when SIGABRT 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++.
