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>>. |
