How to use

You need to link with libprintf2.a (Linux) or printf2.lib (Windows). Add the P2.h header in any place convenient in your project.

An example program:

#include "P2.h"

int main() {
  P2_Init();

  P2_Print("Hello! %d", 123);

  P2_Deinit();
}

First in P2_Init it will try connecting to the server for 5 seconds. If it can't find a server, it will resume the program without logging anything.

Launch Printf2 server, you should find it in GUI folder if you download the GitHub package provided. (Or packaged with make package).

A window should appear. Try launching the example code again. You will see a "Hello 123" log appear.
