Sending a specific SCSI command to a SCSI device in Windows

Question

Does the window have a specific interface on which I can send a specific scsi command, such as a request to an scsi device? I searched the network, found a link to the SCSI Pass Through interface. But it is very vague.

Is there any documentation for this API on how to use it?

#include <iostream>
#include <windows.h>
#include <winioctl.h>
#define ULONG_PTR ULONG
#include <ntddscsi.h> //from SDK
#include <spti.h>      //from DDK 
using namespace std;

    DWORD bytesReturn;
    BYTE bufDataRead[64*1024+10];
    int iRet;        

    hDisk = CreateFile(path,GENERIC_READ | GENERIC_WRITE,     
            FILE_SHARE_READ | FILE_SHARE_WRITE, NULL,OPEN_EXISTING,0,NULL                                 
            );
    if (hDisk ==INVALID_HANDLE_VALUE)  {              
          return 0;
    }
    ZeroMemory(&sptdwb, sizeof(SCSI_PASS_THROUGH_DIRECT_WITH_BUFFER));
    sptdwb.sptd.Length = sizeof(SCSI_PASS_THROUGH_DIRECT);
    sptdwb.sptd.PathId = 0;

            length,
            &sptdwb,
            length,
            &bytesReturn,
            NULL);
    if (0 == iRet)  {

    } else {
    //Check returned data in sptdwb.sptd.DataBuffer.

SCSI covers a huge amount of land. You are talking to a CD / DVD / disc / tape / scanner or what.
