FUNCTION
<<abort>>---abnormal termination of a program

INDEX
	abort

SYNOPSIS
	#include <stdlib.h>
	void abort(void);

DESCRIPTION
Use <<abort>> to signal that your program has detected a condition it
cannot deal with.  Normally, <<abort>> ends your program's execution.

Before terminating your program, <<abort>> raises the exception <<SIGABRT>>
(using `<<raise(SIGABRT)>>').  If you have used <<signal>> to register
an exception handler for this condition, that handler has the
opportunity to retain control, thereby avoiding program termination.

In this implementation, <<abort>> does not perform any stream- or
file-related cleanup (the host environment may do so; if not, you can
arrange for your program to do its own cleanup with a <<SIGABRT>>
exception handler).

RETURNS
<<abort>> does not return to its caller.

PORTABILITY
ANSI C requires <<abort>>.

Supporting OS subroutines required: <<_exit>> and optionally, <<write>>.
