You can lookup the function object on the global object in the context like
this:
v8::Local<v8::Function> foo =
v8::Local<v8::Function>::Cast(context->Global()->Get(v8::String::New("foo")));
and then call it like this:
v8::Handle<v8::Value> args[] = { v8::String::New("arg") };
v8::Local<v8::Value> result = foo->Call(foo, 1, args1);
The result will be empty if an exception occoured. You can use a stack
allocated v8::TryCatch in C++ to catch exceptions.
Take a look at the test "FunctionCall" in test/cctest/test-api.cc.
