示例1: SeekToType

// SeekToType moves the reader to the type specified by the entry,
// optionally resolving typedefs and pointer types. If the reader is set
// to a struct type the NextMemberVariable call can be used to walk all member data.
func (reader *Reader) SeekToType(entry *dwarf.Entry, resolveTypedefs bool, resolvePointerTypes bool) (*dwarf.Entry, error) {
    offset, ok := entry.Val(dwarf.AttrType).(dwarf.Offset)
    if !ok {
        return nil, fmt.Errorf("entry does not have a type attribute")
    }

    // Seek to the first type offset
    reader.Seek(offset)

    // Walk the types to the base
    for typeEntry, err := reader.Next(); typeEntry != nil; typeEntry, err = reader.Next() {
        if err != nil {
            return nil, err
        }

        if typeEntry.Tag == dwarf.TagTypedef && !resolveTypedefs {
            return typeEntry, nil
        }

        if typeEntry.Tag == dwarf.TagPointerType && !resolvePointerTypes {
            return typeEntry, nil
        }

        offset, ok = typeEntry.Val(dwarf.AttrType).(dwarf.Offset)
        if !ok {
            return typeEntry, nil
        }
