#include <time.h>

void main( void )

/* Find the rest of the .c files */

c_file.name, ctime( &( c_file.time_write ) ), c_file.size );
}

_findclose( hFile );
}
}

Grazie, avevo più o meno capito il funzionamento, anche se non ho capito il ruolo della variabile long hfile, potresti spiegarmelo????
