The following sample code shows how to copy the drives object into the Startup folder, so the Drives folder will be opened during system startup:

#define INCL_WINWORKPLACE
#include "os2.h"

HOBJECT    hObjectofDest;
HOBJECT    hObjectofObject;
HOBJECT    hObjectofResult;

hObjectofObject = WinQueryObject("<WP_DRIVES>");
if (hObjectofObject != NULL)
{
  /* WinQueryObject of Drives was successful */
  hObjectofDest = WinQueryObject("<WP_START>");

  if (hObjectofDest != NULL)
  {
    /* WinQueryObject of Startup was successful */
    hObjectofResult = WinCopyObject(hObjectofObject,
                                    hObjectofDest,
                                    0);

    if (hObjectofResult != NULL)
    {
      /* Drives object was successfully moved to the Startup folder */
    }
    else
    {
      /* Copy failed */
    }
  }
}
