Question

Which of the following signals are generated from the hardware?

(a) SIGFPE

(b) SIGILL

(c) SIGSEGV

(d) SIGPE, SIGILL, SIGSEGV

This question was posed to me by my college professor while I was bunking the class.

I would like to ask this question from Process Control System Calls topic in chapter System Programming II – Process Control & Unix System Performance of Unix

Answer 1

Correct choice is (d) SIGPE, SIGILL, SIGSEGV

To explain I would say: Signals can be generated from hardware too like SIGFPE is generated on account of an arithmetic operation, SIGILL is generated for illegal instruction and SIGSEGV is generated for memory access violation. All these signals result in the termination of the process.
