.TH ABORT 3C "Jul 24, 2002"
.SH NAME
abort \- terminate the process abnormally
.SH SYNOPSIS
.LP
.nf
#include <stdlib.h>

\fBvoid\fR \fBabort\fR(\fBvoid\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBabort()\fR function causes abnormal process termination to occur, unless
the signal \fBSIGABRT\fR is being caught and the signal handler does not
return.  The abnormal termination processing includes at least the effect of
\fBfclose\fR(3C) on all open streams and message catalogue descriptors, and the
default actions defined for \fBSIGABRT\fR. The \fBSIGABRT\fR signal is sent to
the calling process as if by means of the \fBraise\fR(3C) function with the
argument \fBSIGABRT\fR.
.sp
.LP
The status made available to \fBwait\fR(3C) or \fBwaitpid\fR(3C) by
\fBabort\fR will be that of a process terminated by the \fBSIGABRT\fR signal.
\fBabort\fR will override blocking or ignoring the \fBSIGABRT\fR signal.
.SH RETURN VALUES
.sp
.LP
The \fBabort()\fR function does not return.
.SH ERRORS
.sp
.LP
No errors are defined.
.SH USAGE
.sp
.LP
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 \fBSIGABRT\fR is neither caught
nor ignored, and the current directory is writable, a core dump may be
produced.
