No, it was just that I DIDN'T KNOW how big P_DATA will be. The packets should
be sent through TCP/IP and contained some other fields. OK, I also can use
classes, but I would have to copy P_DATA and PACKET into a new array which is
much overhead. I did this very often in Turbo Pascal with switched-off range
checking. I wanted to know if a p = (...) new char[n] could replace malloc
and a delete [] (char *) p could replace free. But, the exe file grew if
using this, so that the answer is now irrelevant to me.
