Problem with DLL in Delphi

[himitsu]

Code:

int __declspec(dllexport) __stdcall DIE_scanA   (char     *pszFileName,   char *pszOutBuffer, int nOutBufferSize, unsigned int nFlags);
int __declspec(dllexport) __stdcall DIE_scanW   (wchar_t *pwszFileName, char *pszOutBuffer, int nOutBufferSize, unsigned int nFlags);
int __declspec(dllexport) __stdcall DIE_scanExA(char     *pszFileName,   char *pszOutBuffer, int nOutBufferSize, unsigned int nFlags, char     *pszDataBase);
int __declspec(dllexport) __stdcall DIE_scanExW(wchar_t *pwszFileName, char *pszOutBuffer, int nOutBufferSize, unsigned int nFlags, wchar_t *pwszDataBase);

The output buffer is always AnsiChar,

but that still does not explain the error message.
