Parameters
Revision Defines the revision of the EFI_LOADED_IMAGE structure.
All future revisions will be backward compatible to the current
revision.
ParentHandle Parent image’s image handle. NULL if the image is loaded
directly from the firmware’s boot manager. Type EFI_HANDLE
is defined in Chapter 5.
SystemTable The image’s EFI system table pointer. Type
EFI_SYSTEM_TABLE is defined in Chapter 4.
DeviceHandle The device handle that the EFI Image was loaded from. Type
EFI_HANDLE is defined in Chapter 5.
FilePath A pointer to the file path portion specific to DeviceHandle
that the EFI Image was loaded from. The EFI_DEVICE_PATH
protocol is defined in Chapter 8.
Reserved Reserved. DO NOT USE.
LoadOptionsSize The size in bytes of LoadOptions .
LoadOptions A pointer to the image’s binary load options.
ImageBase The base address at which the image was loaded.
ImageSize The size in bytes of the loaded image.
ImageCodeType The memory type that the code sections were loaded as. Type
EFI_MEMORY_TYPE is defined in Chapter 5.
ImageDataType The memory type that the data sections were loaded as. Type
EFI_MEMORY_TYPE is defined in Chapter 5.
Unload Function that unloads the image. See Unload() .
Description
Each loaded image has an image handle that supports the EFI_LOADED_IMAGE protocol. When
an image is started, it is passed the image handle for itself. The image can use the handle to obtain
its relevant image data stored in the
EFI_LOADED_IMAGE structure, such as its load options.
