ABORT(3) FreeBSD Library Functions Manual ABORT(3)
NAME
abort - cause abnormal program termination
SYNOPSIS
#include <stdlib.h>
void
abort(void);
DESCRIPTION
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.
RETURN VALUES
The abort() function never returns.
SEE ALSO
sigaction(2), exit(3)
STANDARDS
The abort() function conforms to IEEE Std 1003.1-1990 ("POSIX.1").
HISTORY
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.
