On Fri, 14 Dec 2001 12:11:48 +0100, there came a drop of sanity from
"Emile Bosch" <emilebosch AT hotmail DOT com> containing:

A fairly good sample is :
void GetInt(int **ppInt);
int main()
{
int * ppInt;
GetInt(&ppInt);
}
void GetInt(int **pointer)
{
*pointer = new int[50];
for(int n=0;n<50;n++)
(*pointer)[n] = n*14+26;
}
Things like this would be "impossible" to do without pointers to
pointers...
BTW!
Just wrote this directly into my newsreader, don't know if it works...
