PInvoke Marshalling....

Greetings!

I'm trying to call this method in a c# app...

SNAPIDLL_API int __stdcall SNAPI_SetCapabilitiesBuffer(HANDLE
DeviceHandle, unsigned char *pData, long max_length);

So far I've got this:
[DllImport("Dependencies\\SNAPI.DLL")]
public static extern int SNAPI_SetVersionBuffer(IntPtr DeviceHandle,
StringBuilder pData, long max_length);

Keep getting a PInvokeStackImbalance error and I think it's the 2nd paramter
pData because I've referenced the device handler and the long typedef is
pretty obvious.

For the 2nd paramter I've tried the following without success:
byte[]
char[]
string
StringBuilder
[MarshalAs(UnmanagedType.AnsiBStr)] string

HELP!
Thanks.
Dan.
