@defproc[(exit [v any/c #t]) any]{

|
|
Passes @scheme[v] to the current @tech{exit handler}. If the exit
|
|
handler does not escape or terminate the thread, @|void-const| is
|
|
returned.}

@defparam[exit-handler proc (any/c . -> . any)]{
|
|
|
|
A parameter that determines the current @deftech{exit handler}. The
|
|
@tech{exit handler} is called by @scheme[exit].
|
|
|
|
The default @tech{exit handler} in the @exec{mzscheme} executable
|
|
takes any argument and shuts down the OS-level Scheme process. The
|
|
argument is used as the OS-level exit code if it is an exact integer
|
|
between @scheme[1] and @scheme[255] (which normally means
|
|
``failure''); otherwise, the exit code is @scheme[0], (which normally
|
|
means ``success'').}
