Function Documentation

BOOLEAN PeCoffLoaderImageFormatSupported ( IN UINT16  Machine  ) 

Returns TRUE if the machine type of PE/COFF image is supported. Supported does not mean the image can be executed it means the PE/COFF loader supports loading and relocating of the image type. It's up to the caller to support the entry point.

The itanium version PE/COFF loader/relocater supports itanium and EBC image.

Parameters:
Machine Machine type from the PE Header.
Returns:
TRUE if this PE/COFF loader can load the image

FALSE unrecoganized machine type of image.

References FALSE, IMAGE_FILE_MACHINE_EBC, IMAGE_FILE_MACHINE_IA64, and TRUE.

RETURN_STATUS PeHotRelocateImageEx ( IN UINT16 Reloc,
