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>>.
