I know the basics already, I lerned them 4 years ago. I was looking for a way to change the size of an array at runtime, and...

...well, like always I ask something in this forum, I found the solution in the manual myself. And like always I feel like a total jerk. Argh... o.-'

The perfect answer to my question was in the example to sys_malloc, but I always just looked for malloc, where I, of course, found nothing helpful.
Now I understand and it works.

Thx for helping.
