Question

Which library function uses kill to send any signal to the current process?

(a) getc

(b) raise

(c) catch

(d) try

This question was posed to me in unit test.

My question comes from Process Control System Calls topic in portion System Programming II – Process Control & Unix System Performance of Unix

Answer 1

The correct choice is (b) raise

To explain: kill sends a signal but doesn’t necessarily kill a process. Kill system call is used by the library function raise to send any signal to the current process.
