Node Buffer to char array

Question

I have a native NodeJS addon that accepts a Buffer instance as one of it\'s arguments.

I\'m able to convert a char array into a Buffer

Answer 1

Maybe I'm late, but the following code should work:

#include <node.h>
#include <node_buffer.h>

void Test(const FunctionCallbackInfo<Value>& args)
{
  Local<Object> bufferObj = args[0]->ToObject();
  char* bufferData = node::Buffer::Data(bufferObj);
  size_t bufferLength = node::Buffer::Length(bufferObj);
}
