Test Your Knowledge in Computers #268
Difficulty: Easy
In 1936, Turing published his paper 'On Computable Numbers, with an Application to the Entscheidungsproblem'. In this paper, Turing reformulated Kurt Godel's 1931 results on the limits of proof and computation, replacing Godel's universal arithmetic-based formal language with the formal and simple hypothetical devices that became known as Turing machines.

abort(3) [linux man page]

ABORT(3)						     Linux Programmer's Manual							  ABORT(3)

NAME
abort - cause abnormal process termination SYNOPSIS
#include <stdlib.h> void abort(void); DESCRIPTION
The abort() first unblocks the SIGABRT signal, and then raises that signal for the calling process. This results in the abnormal termina- tion of the process unless the SIGABRT signal is caught and the signal handler does not return (see longjmp(3)). If the abort() function causes process termination, all open streams are closed and flushed. If the SIGABRT signal is ignored, or caught by a handler that returns, the abort() function will still terminate the process. It does this by restoring the default disposition for SIGABRT and then raising the signal for a second time. RETURN VALUE
The abort() function never returns. CONFORMING TO
SVr4, POSIX.1-2001, 4.3BSD, C89, C99. SEE ALSO
gdb(1), sigaction(2), exit(3), longjmp(3), raise(3) COLOPHON
