Everything I do results in some problem, I've tried malloc but then converting the strings resulted in my program becoming corrupted.

Heres the code:

auto EnumServices()

auto schSCManager = OpenSCManager(null, null, SC_MANAGER_ALL_ACCESS);
    if (NULL == schSCManager)
        print("OpenSCManager failed (%d)\n", GetLastError());
return null; // Why can't we return a null? Surely we don't have to cast a null in to a typeof null?
        import core.stdc.stdlib;
        DWORD dwBytesNeeded, dwCount, lpResumeHandle, resume;


        ENUM_SERVICE_STATUS_PROCESS[5000] services;
auto res = SVC.EnumServicesStatusExA(schSCManager, SC_ENUM_TYPE.SC_ENUM_PROCESS_INFO, servicesType, SERVICE_STATE_ALL, cast(ubyte*)services.ptr, 5000*ENUM_SERVICE_STATUS_PROCESS.sizeof, &dwBytesNeeded, &dwCount, &resume, cast(const(char)*)null);
        for(int i = 0; i < dwCount; i++)
                auto s = services[i].lpServiceName;

        return services;

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.
