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>>.
