WINDEV ->C<->D buffer, unsigned byte

Hi,
yeah the title is a bit confusing. So what's the story ?
atm I am creating a tiny crypto dll for Windev. Problem is based on parameter passing.

//C code
void rc2_decrypt( const unsigned short xkey[64],
                   unsigned char *plain,
                   const unsigned char *cipher )
{
         unsigned x76, x54, x32, x10, i;

         x76 = (cipher[7] << 8) + cipher[6];
.........

Not yet a DLL function but I am not a C/C++ fan, so here the D port.

//D programming language 
export extern(Windows) /*create DLL function */
void rc2_decrypt( const(ushort)[64] xkey, ubyte* plain, const(ubyte)* cipher )

ubyte is unsigned byte, allready more readable, right ?

But instead of using a pointer to unsigned byte, I would prefer to use arrays:...

//D programming language  
export extern(Windows) /*create DLL function using arrays*/
void rc2_decrypt( const(ushort)[64] xkey, ubyte[] plain, const(ubyte)[] cipher )

In order to use the array based DLL function, I just can hope that WINDEVs buffer is usable:

// WINDEV
plain is  buffer = "DecryptMePlease" // the rc2-decrypt plain parameter

Any ideas ?

Edit [ D is C ABI compatible, ABI not API ]

Sorry I can't drive any tests: Most of my hardware is damaged due high voltage accident.
Hope, I'll get new toys within the next 2 days.
