RunOnEnd : Run a lambda in destructor

CodeQL Build Status


  • A simpler "run on end" vs. the custom deletor available via std::unique_ptr<>. It is important to note that we do not provide an "owning" helper as this is better accomplished via the destructor code for std::unique_ptr<>.
  • Use the nuget SiddiqSoft.RunOnEnd
  • Copy paste..whatever works.


The utility can be used to ensure you cleanup within a scope, update some global variable or use the definition to build your own auto-cleanup.

Consider the following example where the utility UseWinsock builds on RunOnEnd for its functionality.

struct UseWinsock : private siddiqsoft::RunOnEnd
    UseWinsock() noexcept
        : m_rc(E_FAIL)
        , siddiqsoft::RunOnEnd([&]() {
            if (m_rc == S_OK) WSACleanup();
        ZeroMemory(&m_wsaData, sizeof(m_wsaData));
        m_rc = WSAStartup(MAKEWORD(2, 2), &m_wsaData);
        m_rc = (m_rc == 0) ? S_OK : WSAGetLastError();

    operator bool() { return (m_rc == S_OK); }

    int     m_rc;
    WSADATA m_wsaData;
