/**
Returns information about a deferred image.
This function returns information about a single deferred image. The deferred images are
numbered consecutively, starting with 0. If there is no image which corresponds to
ImageIndex, then EFI_NOT_FOUND is returned. All deferred images may be returned by
iteratively calling this function until EFI_NOT_FOUND is returned.
Image may be NULL and ImageSize set to 0 if the decision to defer execution was made
because of the location of the executable image, rather than its actual contents.
@param[in] This Points to this instance of the EFI_DEFERRED_IMAGE_LOAD_PROTOCOL.
@param[in] ImageIndex Zero-based index of the deferred index.
@param[out] ImageDevicePath On return, points to a pointer to the device path of the image.
The device path should not be freed by the caller.
@param[out] Image On return, points to the first byte of the image or NULL if the
image is not available. The image should not be freed by the caller
unless LoadImage() has been successfully called.
@param[out] ImageSize On return, the size of the image, or 0 if the image is not available.
@param[out] BootOption On return, points to TRUE if the image was intended as a boot option
or FALSE if it was not intended as a boot option.
@retval EFI_SUCCESS Image information returned successfully.
@retval EFI_NOT_FOUND ImageIndex does not refer to a valid image.
@retval EFI_INVALID_PARAMETER ImageDevicePath is NULL or Image is NULL or ImageSize is NULL or
BootOption is NULL.
