[En-Nut-Discussion] Bug #1799374: NutRegisterCgi() Parameter 1

[Alain M.]

I don't understand something in what you say:
1) if you have a string that is NOT const and you pass it to a function 
that has a cont parameter, it is ok and no error messages
2) once a file is open, you will not use it's name anymore, so it can be 
discated anytime

Alain
BTW, the example bellow could crash because the second string is bigger 
than the first...
