The ExtractSection() function processes the input section and

processed. OutputBuffer OutputBuffer is
allocated from PEI permanent memory and contains

@param InputSection A pointer to the input buffer, which contains
the input section to be processed.
@param OutputBuffer A pointer to a caller-allocated buffer, whose
size is specified by the contents of OutputSize.
