NAME

6       abort - cause abnormal process termination
7

SYNOPSIS

9       #include <stdlib.h>
10
11       void abort(void);
12

DESCRIPTION

14       The  abort()  first  unblocks  the SIGABRT signal, and then raises that
15       signal for the calling process.  This results in the abnormal  termina‐
16       tion  of the process unless the SIGABRT signal is caught and the signal
17       handler does not return (see longjmp(3)).
18
19       If the abort() function causes process termination,  all  open  streams
20       are closed and flushed.
21
22       If  the SIGABRT signal is ignored, or caught by a handler that returns,
23       the abort() function will still terminate the process.  It does this by
24       restoring the default disposition for SIGABRT and then raising the sig‐
25       nal for a second time.
26

RETURN VALUE

28       The abort() function never returns.
