Heres the code:

What is the signature of the function you are trying to call?
(make sure its correct :))
Allocating 5000 services may blow your stack.
you can just use `services.sizeof` instead of
`5000*ENUM_SERVICE_STATUS_PROCESS.sizeof`.
You are returning that massive static array, remember that static
arrays are value types in D so that will get copied. Consider
allocating the array and returning a slice of it.
Note also that `lpServiceName` is probably a `char*` so
drefferencing will give you a char, not a string. Use
std.string.fromStringz(?) for that.
