#include <rw/trace/RWTraceMultiClientFilter.h>

RWTraceMultiClientFilter is a filter that accepts multiple clients and forwards trace events to them.

The following example creates two clients; one displays messages on the screen, and the other saves them to a file. This example can be found in examples/trace/example2.cpp.

#define RW_USER_TRACE_LEVEL 8
#include <rw\trace\trace.h>

#include <fstream.h>

int main() 
{
  ofstream traceLog("trace.log");
  RWTraceOstreamClient myFileTraceClient(traceLog);
  RWTraceOstreamClient myCerrTraceClient(cerr);

  RWTraceMultiClientFilter myMultiFilter;                  // 1

  // first: connect two clients to multi client filter 
  myFileTraceClient.connect(myMultiFilter);                // 2
  myCerrTraceClient.connect(myMultiFilter);
    
  // last: connect filter to singleton manager
  myMultiFilter.connectToManager();                        // 3

  RW_USER_TRACEABLE_FUNCTION("main");                      // 4

  RW_USER_TRACE_DEBUG("Picked up pencil.");
  RW_USER_TRACE_TEST("Visual inspection of pencil complete.");
  RW_USER_TRACE_INFO("Doodling!");
  ...
  return 0;
}
