Redirecting standard output to syslog

Question

I\'m planning to package OpenTibia Server for Debian. One of the things I want to do is add startup via /etc/init.d and daemonization of the otserv

You can redirect any stream in C++ via the rdbuf() command. This is a bit convoluted to implement but not that hard.

You need to write a streambuf that would output to syslog on overflow(), and replace the std::cout rdbuf with your streambuf.

An example, that would output to a file (no error handling, untested code)

#include 
#include 
using namespace std;

int main (int argc, char** argv) {
   streambuf * yourStreamBuffer = NULL;
   ofstream outputFileStream;
   outputFileStream.open ("theOutputFile.txt");

   yourStreamBuffer = outputFileStream.rdbuf();
   cout.rdbuf(yourStreamBuffer);

   cout << "Ends up in the file, not std::cout!";

   outputFileStream.close();

   return 0;
 }
