我不明白这个库是如何工作的,而且文档是我见过的最糟糕的文档之一。如何将存档中存储的文本文件读入内存?我什至使用正确的功能吗?

        // Reading the raw zip file into memory
        std::ifstream raw_file("archive.zip", std::ios::binary);
        auto buffer = static_cast<std::ostringstream&>(
                  std::ostringstream{} << raw_file.rdbuf())
                  .str();

        struct archive* a = archive_read_new();
        struct archive_entry* entry;
        archive_read_support_compression_all(a);
        archive_read_support_format_raw(a);
        int r =
            archive_read_open_memory(a, buffer.data(), buffer.size());
        while (archive_read_next_header(a, &entry) == ARCHIVE_OK) {
            archive_read_data(a, buffer.data(), buffer.size());
        }

        // This prints out binary data instead of text files stored inside the archive
        std::cout << buffer << std::endl;
        r = archive_read_free(a);
