Hello,
Sorry if this is an obvious question, but I'm trying to pass a native c++
data pointer through when setting up a function template for access within
a callback.
So for example in the code below, if I wanted to pass 'buffer' through for
use within the LogCallback, what is the best way to achieve it?
static char buffer[1024];
Handle<ObjectTemplate> global = ObjectTemplate::New();
global->Set(String::New("log"), FunctionTemplate::New(LogCallback));
Looking at FunctionTemplate I see this constructor is available...
static Local<FunctionTemplate> New(
FunctionCallback callback = 0,
Handle<Value> data = Handle<Value>(),
Handle<Signature> signature = Handle<Signature>(),
int length = 0);
So do I have to wrap this buffer pointer into a Handle<Value>() somehow and
supply it as the 2nd data argument?
Then I could get the value back using the Data() method of the AccessorInfo?
class PropertyCallbackInfo {
public:
V8_INLINE(Local<Value> Data() const);
V8_INLINE(Local<Object> This() const);
V8_INLINE(Local<Object> Holder() const);
Or perhaps I'm on the wrong track...?
Thanks,
Mark.
