  UEFI 2.2 Deferred Image Load Protocol definition.\r
\r
  This protocol returns information about images whose load was denied because of security\r
  considerations. This information can be used by the Boot Manager or another agent to reevaluate the\r
  images when the current security profile has been changed, such as when the current user profile\r
  changes. There can be more than one instance of this protocol installed.\r

  Returns information about a deferred image.\r
\r
  This function returns information about a single deferred image. The deferred images are numbered\r
  consecutively, starting with 0.  If there is no image which corresponds to ImageIndex, then\r
  EFI_NOT_FOUND is returned. All deferred images may be returned by iteratively calling this\r
  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 because\r
  of the location of the executable image rather than its actual contents.  record handle until\r
  there are no more, at which point UserInfo will point to NULL.\r
