How can I uninject the injected lib about injector HOT 2 CLOSED

    DWORD pid = ...process id of the target process...;

    // find the base address of the library in the target process.
    HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, pid);
    if (hSnapshot == INVALID_HANDLE_VALUE) {

        if (...check `me.szModule` or `me.szExePath`...) {
            break;
        }
    }
    if (!ok) {
        ...error handling...
    }
    CloseHandle(hSnapshot);
    // `me.modBaseAddr` is the base address of the library to be uninjected.

    // Call FreeLibarry in the target process.
    HANDLE hProcess = OpenProcess(PROCESS_CREATE_THREAD, FALSE, pid);
    if (hProcess == NULL) {
        ...error handling...
    }
    HMODULE kernel32 = GetModuleHandleA("kernel32");
    LPTHREAD_START_ROUTINE func_addr = (LPTHREAD_START_ROUTINE)GetProcAddress(kernel32, "FreeLibrary");
    HANDLE hThread = CreateRemoteThead(hProcess, NULL, 0,  func_addr, me.modBaseAddr, 0, NULL);
    if (hThread == NULL) {
        ...error handling...
    }
    WaitForSingleObject(hThread, INFINITE);
