Redirect stream in C# with parallel (independant) mosel instances

So you advice to create only one XPRM object and to share it between all the threads. Is this correct ?

But in this case, all the threads have to write log at the same place.

So a code where each thread writes a specific log file is not possible. For example :

Main method :

Parallel.For(0, 10, i =>
{
       MyMethod(i);
});

MyMethod(int i) :

XPRM mosel = XPRM.Init();
 
string fichierLog = Path.GetFullPath($@"LogMosel{i}.txt");
StreamWriter sw = new StreamWriter(fichierLog, false);
XPRMIOCallbackOutputText callback = (XPRMModel model, object obj, string line) =>
{
       Console.Write(line);
       sw.Write(line);
};
 
mosel.SetDefaultStream(XPRMStreamType.F_OUTPUT, mosel.CreateIOCallback(callback));
mosel.SetDefaultStream(XPRMStreamType.F_ERROR, mosel.CreateIOCallback(callback));
