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.

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.
|
|
|
|
@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 called successfully.
|
|
@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.
