There is, but only if you use C++ glue to bind your C API to v8's C++ API,
which in turn binds to JS space.
If i may be so bold as to toot my own horn for a moment, i believe i've
implemented the world's simplest-to-use binding mechanism for wrapping C
functions (from C++) in v8. Here's an example of all the code one needs to
bind sleep() to v8:
jsObj->Set( String::New("sleep"), FunctionTemplate::New(
convert::FunctionForwarder<1>::Invocable<unsigned int,unsigned
int,::sleep>
)->GetFunction() );
About 50% of that code is required by v8 (i.e. unavoidable, regardless of
the wrapping framework) and the other 50% is invoking one of my templates
which creates a new v8::InvocationCallback function (with compile-time type
safety and no dynamic memory costs) which acts a proxy for sleep().
