communication between native-app and chrome-extension

Question

I have a native app written in c++ and a chrome-extension.

I am communicating between them using \'chrome native messaging\'.

Native-App code:

Answer 1

This works for me:

 int main(int argc, char* argv[])
 {

 std::cout.setf( std::ios_base::unitbuf ); //instead of "<< eof" and "flushall"
 unsigned int a, c, i, t=0;
 std::string inp;  

 do {

 inp="";
 t=0;
 // Sum the first 4 chars from stdin (the length of the message passed).
  for (i = 0; i <= 3; i++) {
    t += getchar();
  }

  // Loop getchar to pull in the message until we reach the total
  //  length provided.
  for (i=0; i < t; i++) {
    c = getchar();
    inp += c;
  }

//Collect the length of the message
unsigned int len = inp.length();
//// We need to send the 4 btyes of length information
std::cout << char(((len>>0) & 0xFF))
          << char(((len>>8) & 0xFF))
          << char(((len>>16) & 0xFF))
          << char(((len>>24) & 0xFF));
//// Now we can output our message
std::cout << inp;
}
