ABORT(3C) Standard C Library Functions ABORT(3C)
NAME
abort - terminate the process abnormally
SYNOPSIS
#include <stdlib.h>
void abort(
void);
DESCRIPTION
The
abort() function causes abnormal process termination to occur, unless
the signal
SIGABRT is being caught and the signal handler does not
return. The abnormal termination processing includes at least the effect
of
fclose(3C) on all open streams and message catalogue descriptors, and
the default actions defined for
SIGABRT. The
SIGABRT signal is sent to
the calling process as if by means of the
raise(3C) function with the
argument
SIGABRT.
The status made available to
wait(3C) or
waitpid(3C) by
abort will be
that of a process terminated by the
SIGABRT signal.
abort will override
blocking or ignoring the
SIGABRT signal.
RETURN VALUES
The
abort() function does not return.
ERRORS
No errors are defined.
USAGE
Catching the signal is intended to provide the application writer with a
portable means to abort processing, free from possible interference from
any implementation-provided library functions. If
SIGABRT is neither
caught nor ignored, and the current directory is writable, a core dump
may be produced.
