Functions

func Load

func Load(l *loader.Loader, arch *sys.Arch, localSymVersion int, input *bio.Reader, pkg string, length int64, pn string) (textp []loader.Sym, rsrc []loader.Sym, err error)

Load loads the PE file pn from input. Symbols are written into syms, and a slice of the text symbols is returned. If an .rsrc section or set of .rsrc$xx sections is found, its symbols are returned as rsrc.

Types
