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 (as though raise(3) was called). This results in the abnormal termination 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.
