This may sound like a stupid question but for the life of me I can't
figure this out.  It involves pointers which I was never really good
with.  I hope someone can (_nicely_) help me out here...

I've got a structure:

typedef struct { int h,c; } buf_data;

and I define two variables and allocate memory for them:

tbuf *buf_data;
bbuf *buf_data;
tbuf = new buf_data[video.max_x];
bbuf = new buf_data[video.max_x];

and now I want to copy the values from bbuf to tbuf.  The following
should work shouldn't it?

tbuf = bbuf;

because it would copy the address of bbuf into tbuf right?  Or am I
totally wrong?  I've tried

tbuf = &bbuf;

but C++ doesn't like that.

Any ideas?
