Loads an EFI image into memory and returns a handle to the image with extended parameters.

@param This Calling context
|
|
@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 Image handle for output.
|
|
@param EntryPoint 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 Image was not loaded due to insufficient
|
|
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.
