TRAD_SYNOPSIS |

#include |
|
|

void abort(); |

DESCRIPTION |
|
|
27 |
Use <> to signal that your program has detected a condition it |
|
|
28 |
cannot deal with. Normally, <> ends your program's execution. |
|
|
29 |
|
|
|
30 |
Before terminating your program, <> raises the exception <> |
|
|
31 |
(using `<>'). If you have used <> 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, <> 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 <> |
|
|
38 |
exception handler). |
|
|
39 |
|
|
|
40 |
RETURNS |
|
|
41 |
<> does not return to its caller. |
|
|
42 |
|
|
|
43 |
PORTABILITY |
|
|
44 |
ANSI C requires <>. |
|
|
45 |
|
|
|
46 |
Supporting OS subroutines required: <<_exit>> and optionally, <>. |
