FUNCTION

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

INDEX

        abort

ANSI_SYNOPSIS

        #include <stdlib.h>

        void abort(void);

TRAD_SYNOPSIS

        #include <stdlib.h>

        void abort();

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>>.
