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.
