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.
