Can Standard C Catch Memory Access Violation Exceptions?

Can Access Violation Exceptions Be Caught Using Standard C ?

Catching memory access violation exceptions in C without relying on Microsoft-specific libraries has been a persistent challenge. However, a creative solution has emerged that utilizes signal handling to intercept access violations and handle them seamlessly.

To set up signal handling, a function called SignalHandler is defined to handle the SIGSEGV signal, which indicates an access violation. Within this function, an exception is thrown using the throw keyword.

In the main() function, the signal() function is used to associate the SignalHandler with the SIGSEGV signal. The try-catch block is then used to capture the exception thrown by the signal handler.

Within the catch block, the exception message is printed to the console, allowing the programmer to debug the issue. Crucially, by re-throwing the exception, the program can continue execution without being terminated by the access violation.

This technique allows standard C programs to detect and handle access violations in a controlled manner, providing a valuable tool for debugging and error handling. It's important to note that this approach is intended for educational purposes and should not be used in production code as it may mask underlying problems.
