Load Pe32 Image protocol enables loading and unloading EFI images into memory and executing those images.
|
|
This protocol uses File Device Path to get an EFI image.

@param ParentImageHandle The caller's image handle.
|
|
@param FilePath The specific file path from which the image is loaded.
|

@param SourceBuffer If not NULL, a pointer to the memory location containing a copy of

the image to be loaded.
|
|
@param SourceSize The size in bytes of SourceBuffer.
|
|
@param DstBuffer The buffer to store the image.
|
|
@param NumberOfPages For input, specifies the space size of the image by caller if not NULL.
|
|
For output, specifies the actual space size needed.
|

@param ImageHandle The image handle for output.

@param EntryPoint The image entry point for output.

@param Attribute The bit mask of attributes to set for the load PE image.

@retval EFI_SUCCESS The image was loaded into memory.
|
|
@retval EFI_NOT_FOUND The FilePath was not found.
|
|
@retval EFI_INVALID_PARAMETER One of the parameters has an invalid value.
|
|
@retval EFI_UNSUPPORTED The image type is not supported, or the device path cannot be
|
|
parsed to locate the proper protocol for loading the file.
|
|
@retval EFI_OUT_OF_RESOURCES The image was not loaded due to insufficient memory resources.
|
|
@retval EFI_LOAD_ERROR Image was not loaded because the image format was corrupt or not
|
|
understood.
|
|
@retval EFI_DEVICE_ERROR Image was not loaded because the device returned a read error.
|
|
@retval EFI_ACCESS_DENIED Image was not loaded because the platform policy prohibits the
|
|
image from being loaded. NULL is returned in *ImageHandle.
|
|
@retval EFI_SECURITY_VIOLATION Image was loaded and an ImageHandle was created with a
|
|
valid EFI_LOADED_IMAGE_PROTOCOL. However, the current
|
|
platform policy specifies that the image should not be started.
