Function returns BYTE array

I want my function to return a BYTE array. The function is as follows.

BYTE sendRecieveData(BYTE control, unsigned int value){

//Open connection to LAC
HANDLE LACOutpipe;
HANDLE LACInpipe;
LACOutpipe=openConnection(MP_WRITE);
LACInpipe=openConnection(MP_READ);

//declare variables
BYTE bufDataOut[3];
BYTE bufDataIn[3];
DWORD bufInProcess;
DWORD bufOutProcess;


//sets CONTROL
bufDataOut[0]=control;

//sets DATA to be sent to LAC
BYTE low_byte = 0xff & value;
BYTE high_byte = value >> 8;
bufDataOut[1]=low_byte;
bufDataOut[2]=high_byte;

MPUSBWrite(LACOutpipe,bufDataOut,3,&bufOutProcess,1000);
MPUSBRead(LACInpipe,bufDataIn,3,&bufInProcess,1000);
MPUSBClose(LACOutpipe);
MPUSBClose(LACInpipe);

return bufDataIn[3];
}

It doesn't return a byte array and when I change BYTE to BYTE[] or BYTE[3] it gives me an error.
