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.
