[Vala] Dereferencing a pointer

[regnardet gmx com]

A thing in SDL requires dereferencing a pointer in order to work. In C the expression is:
*pointer = integer;

pointer is void* and integer is a uint.

Can this be done in Vala?

You need this when drawing a pixel on screen in SDL:

All the code leading up to this can be implemented just fine in Vala and SDL.Surface.pixels gives you the 
void* pointer.
