Help with DLL

Hi all,
I am trying to access a function in C from a DLL. The function is defined like this:

int32_t __cdecl AnalyseFile (STRCTYPE filename);

and STRCTYPE is defined as LPCWSTR in C. How do I declare this in Delphi?

I tried this but ti doesn't seem to work:

function AnalyseFile(newPath: PWideChar): LongWord; cdecl;

and I call it like this: AnalyseFile(PWideChar('Mypath'));

Anyone can spot what I am doing wrong?

Thanks

UPDATE: I had mistakenly written that the initial C declarion was stdcall instead of cdecl. I correct it now
