Locking the Vertex Buffer

[ThePentiumGuy]

hey,

in Unmanaged C++ when you try to lock the Vertex buffer you need to do something like this (off the top of my head)

 

VB->Lock(0, (void**)&vertices,0)

 

err.. i dont remmeber exactly, but i remember that the (void**)&vertices argument is there somewehre

 

i know the parenthesees specifies like a CType

for example

 

int x;

 

x = (float) 1 / (float) 2

 

*i think* lol

 

but why is void a pointer to a pointer and why would you want vertices to be converted to the void type?,

Don't worry too much. That's just how it is in c world. Everything there is by value, you have no reference types. So in this case it's the equivalent of passing an array byref. They have to cast to void since that's the declaration of the function and it's an upward cast and that must be explicit in c.

wow..

complicated explanation,

 

thanks (for letting me know at least that there is a reason behind this),
