示例1: main
int main(int argc, char** argv) {
named_mutex mutex(open_or_create, "grapevine_collect_files");
scoped_lock<named_mutex> lock(mutex);

CharAllocator charAllocator (segment.get_segment_manager());
StringAllocator stringAllocator (segment.get_segment_manager());
MyVector *fileList = segment.find_or_construct<MyVector>("file_list")(stringAllocator);
