This gave me a good head start. However, my program crashes at function->Call statement.
Can you please tell me what values function_value, function_name and function are supposed to take.I have also populated argv with random values since I am not using them in my function. If that could also be a reason for the crash, please let me know. This is my JS code : Local<String> source = *String::NewFromUtf8(isolate, "'function test_function() {var match = 0; return match+10;}'",* * NewStringType::kNormal).ToLocalChecked();* *Thanks,* *Kavin* On Friday, August 4, 2017 at 3:29:23 PM UTC-7, Jeremy Bettis wrote: > > What I do to call a function is to use > > v8::Local<v8::Value> function_value; > context->Global()->Get(context, function_name).ToLocal(&function_value); > v8::Local<v8::Function> function = > v8::Local<v8::Function>::Cast(function_value); > const int argc = arguments.size(); > std::vector<v8::Local<v8::Value>> argv(argc); > // populate the argv somehow > function->Call(context, context->Global(), argc, argv.data()); > > On Fri, Aug 4, 2017 at 4:17 PM, Kavin Mani <kavin...@gmail.com > <javascript:>> wrote: > >> Hi, >> >> I am new to V8 engine and starting to experiment things.
