C++ (Cpp) CreateRuntime Examples

Example #1

File: ch.cpp Project: mjsabby/ChakraCore

HRESULT CreateAndRunSerializedScript(const char* fileName, LPCSTR fileContents, char *fullPath)
{
    HRESULT hr = S_OK;
    JsRuntimeHandle runtime = JS_INVALID_RUNTIME_HANDLE;
    JsContextRef context = JS_INVALID_REFERENCE, current = JS_INVALID_REFERENCE;
    BYTE *bcBuffer = nullptr;
    DWORD bcBufferSize = 0;
    IfFailGo(GetSerializedBuffer(fileContents, &bcBuffer, &bcBufferSize));

    // Bytecode buffer is created in one runtime and will be executed on different runtime.

    IfFailGo(CreateRuntime(&runtime));
    chRuntime = runtime;

    IfJsErrorFailLog(ChakraRTInterface::JsCreateContext(runtime, &context));
    IfJsErrorFailLog(ChakraRTInterface::JsGetCurrentContext(&current));
    IfJsErrorFailLog(ChakraRTInterface::JsSetCurrentContext(context));

    // Initialized the WScript object on the new context
    if (!WScriptJsrt::Initialize())
    {
        IfFailGo(E_FAIL);
    }

    IfFailGo(RunScript(fileName, fileContents, bcBuffer, fullPath));

Error:
    if (current != JS_INVALID_REFERENCE)
    {
        ChakraRTInterface::JsSetCurrentContext(current);
    }

    if (runtime != JS_INVALID_RUNTIME_HANDLE)
    {

    }

    if (bcBuffer != nullptr)
