Salve a tutti...qualcuno potrebbe fornirmi un link da cui prelevare un
elenco dei parametri accettati dalla funzione system("") sotto windows?
Grazie

 elenco dei parametri accettati dalla funzione system("") sotto windows?
La tua domanda e' Off-Topic. La lista di "parametri" che system accetta 
sotto windows dipende esclusivamente da windows e non dal C e questo NG si 
interessa di C.
Per cio' che riguarda il C, system() accetta qualsiasi stringa e la passa al 
sistema operativo che eseguira' la chiamata se e' valida. Per il C quindi, 
system("jsdkl dskfdkdfklds sd l"); e' perfettamente valida!
Windows in particolare trovera' valido solo un determinato set di stringhe.
Alcuni comandi windows li puoi avere digitando "help" dalla console di 
windows, vedi in fondo alla mail.
Nota pero' che la lista non puo' essere completa in quanto se hai un 
programma che si chiama pippo nella stessa directory in cui gira il tuo 
programma, system("pippo") eseguira' tale programma, system("calc") invece 
dovrebbe far partire la calcolatrice indipendentemente dalla directory in 
cui ti trovi (e' nel cosi' detto path).
HTH,
Tommaso

 elenco dei parametri accettati dalla funzione system("") sotto windows?
Semplicemente una stringa, system() è una funzione standard.
Viene istanziata la shell del sistema operativo, e le viene passato il
comando.  Anche se per usi "professionali", ci si rifà sempre alle API del
sistema operativo.  Ad esempio, sotto Windows si usa per la maggiore
ShellExecuteEx.

Be', formalmente non lo è :-)
system() è una funzione standard che accetta una stringa ;-)
