/**\r
  Returns information about a deferred image.\r
\r
  This function returns information about a single deferred image. The deferred images are\r
  numbered consecutively, starting with 0.  If there is no image which corresponds to\r
  ImageIndex, then EFI_NOT_FOUND is returned. All deferred images may be returned by\r
  iteratively calling this function until EFI_NOT_FOUND is returned.\r
  Image may be NULL and ImageSize set to 0 if the decision to defer execution was made\r
  because of the location of the executable image, rather than its actual contents.\r

  @param[in]  ImageIndex       Zero-based index of the deferred index.\r
  @param[out] ImageDevicePath  On return, points to a pointer to the device path of the image.\r

  @param[out] Image            On return, points to the first byte of the image or NULL if the\r
                               image is not available. The image should not be freed by the caller\r
                               unless LoadImage() has been successfully called.\r
  @param[out] ImageSize        On return, the size of the image, or 0 if the image is not available.\r
  @param[out] BootOption       On return, points to TRUE if the image was intended as a boot option\r
                               or FALSE if it was not intended as a boot option.\r
