Exception Handling in C without C++ in Linux

Question

Does Linux provide an exception handling in C without resorting to C++? Or, what might be the best way to implement such an exception handling? The goal is to avoid to check return codes for every function called, but do something like in C++ that is thread safe and easily portable.

Answer 1

You can handle the signals by writing your signal handlers for it. Some of these signals documented at GNU are:

• Program Error Signals: Used to report serious program errors.
• Termination Signals: Used to interrupt and/or terminate the program.
• Alarm Signals: Used to indicate expiration of timers.
• Asynchronous I/O Signals: Used to indicate input is available.
• Job Control Signals: Signals used to support job control.
• Operation Error Signals: Used to report operational system errors.
• Miscellaneous Signals: Miscellaneous Signals.
• Signal Messages: Printing a message describing a signal

You can get more info in depth about this here. It states the following which I suppose is what you are looking for:

If you anticipate an event that causes signals, you can define a handler function and tell the operating system to run it when that particular type of signal arrives.

I've never heard of Linux providing anything like that, but this page describes a third-party exception handling library for C: http://www.on-time.com/ddj0011.htm I haven't been able to find the download link, though.
