abort —
cause abnormal program termination
#include
<stdlib.h>
void
abort(
void);
The
abort() function causes abnormal program
termination to occur, unless the signal
SIGABRT is being caught and the signal
handler does not return.
Some implementations may flush output streams before terminating. This
implementation does not.
The
abort() function never returns.

exit(3)
The
abort() function conforms to
IEEE Std 1003.1-1990
(“POSIX.1”).
The
abort() function first appeared in
Version 5 AT&T UNIX.
Historically, previous standards required
abort() to flush and close output streams,
but this conflicted with the requirement that
abort() be async signal safe. As a result,
the flushing requirement was dropped.
