Detailed Description

UEFI 2.2 Deferred Image Load Protocol definition.

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

Typedef Documentation

typedef EFI_STATUS(EFIAPI * EFI_DEFERRED_IMAGE_INFO)(IN EFI_DEFERRED_IMAGE_LOAD_PROTOCOL *This, IN UINTN ImageIndex, OUT EFI_DEVICE_PATH_PROTOCOL **ImageDevicePath, OUT VOID **Image, OUT UINTN *ImageSize, OUT BOOLEAN *BootOption)

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. record handle until there are no more, at which point UserInfo will point to NULL.

Parameters:
[in] This Points to this instance of the EFI_DEFERRED_IMAGE_LOAD_PROTOCOL.
[in] ImageIndex Zero-based index of the deferred index.
[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.
[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 called successfully.
[out] ImageSize On return, the size of the image, or 0 if the image is not available.
[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.
Return values:
EFI_SUCCESS Image information returned successfully.
EFI_NOT_FOUND ImageIndex does not refer to a valid image.
EFI_INVALID_PARAMETER ImageDevicePath is NULL or Image is NULL or ImageSize is NULL or BootOption is NULL.
