ANSI_SYNOPSIS
19
        #include <stdlib.h>
20
        void abort(void);

TRAD_SYNOPSIS
23
        #include <stdlib.h>
24
        void abort();

DESCRIPTION
27
Use <<abort>> to signal that your program has detected a condition it
28
cannot deal with.  Normally, <<abort>> ends your program's execution.
29
 
30
Before terminating your program, <<abort>> raises the exception <<SIGABRT>>
31
(using `<<raise(SIGABRT)>>').  If you have used <<signal>> to register
32
an exception handler for this condition, that handler has the
33
opportunity to retain control, thereby avoiding program termination.
34
 
35
In this implementation, <<abort>> does not perform any stream- or
36
file-related cleanup (the host environment may do so; if not, you can
37
arrange for your program to do its own cleanup with a <<SIGABRT>>
38
exception handler).
39
 
40
RETURNS
41
<<abort>> does not return to its caller.
42
 
43
PORTABILITY
44
ANSI C requires <<abort>>.
45
 
46
Supporting OS subroutines required: <<_exit>> and optionally, <<write>>.
