List folders and item subjects

The following example shows you how to open a PST file, list all folder names and print the subject of each item.

C++ example

#include <iostream>
#include <memory>
#include <vector>

#include "independentsoft/pst/pst_file.hpp"
#include "independentsoft/pst/folder.hpp"
#include "independentsoft/pst/item.hpp"

using namespace independentsoft::pst;

static std::string toUtf8(const text& s)
{
    std::string result;
    for (char16_t c : s)
    {
        if (c < 0x80)
        {
            result += static_cast<char>(c);
        }
        else if (c < 0x800)
        {
            result += static_cast<char>(0xC0 | (c >> 6));
            result += static_cast<char>(0x80 | (c & 0x3F));
        }
        else
        {
            result += static_cast<char>(0xE0 | (c >> 12));
            result += static_cast<char>(0x80 | ((c >> 6) & 0x3F));
            result += static_cast<char>(0x80 | (c & 0x3F));
        }
    }
    return result;
}

int main()
{
    PstFile file("c:\\testfolder\\Outlook.pst");

    Folder* startFolder = file.mailbox_root();

    std::vector<Folder> folders = startFolder->get_folders(true);

    for (size_t i = 0; i < folders.size(); i++)
    {
        Folder& folder = folders[i];

        std::cout << "Folder: " << toUtf8(folder.display_name()) << std::endl;

        std::vector<std::shared_ptr<Item>> items = folder.get_items();

        for (size_t j = 0; j < items.size(); j++)
        {
            std::cout << "  Subject: " << toUtf8(items[j]->subject) << std::endl;
        }

        std::cout << "----------------------------------------------------------------" << std::endl;
    }

    file.close();
    return 0;
}
