Use C's.  It's in std.c.stdlib.  It's called exit, takes an int and returns the
exit code provided by the caller to the OS upon termination.

Hi, I am trying it but my compiler does not find the std.c.stdlib 
module. I am using one of the latest versions. Has it been 
removed?

You're replying to a post that's nearly 11 years old. The C bindings were
moved to druntime quite some time ago. The bindings for C's standard library
are in the package core.stdc. So, the bindings for C's stdlib header are in
core.stdc.stdlib.

Thanks man. Importing core.stdc.stdlib really worked. :)

Gonna take this opportunity to bring up two related concerns.

First: when you exit the program via exit(), module destructors 
will not be run. As a result, any modules that rely on this, such 
as database drivers that close file handles, flush caches to 
disk, etc. will not get a chance to react.

On the other hand, you will also sidestep issue 19978 which notes 
that sometimes, D programs (with daemon threads) just randomly 
crash on exit and nobody knows why.

So you know, you win some, you lose some. :-)

Calling exit is akin to just shooting your process in the head.
