The short answer is: `(_ptr io _VkInstance)` does not mean that a
pointer to a `_VkInstance` happens on the Racket side. It means that a
`_VkInstance` (not a pointer to a `_VkInstance`) happens on the Racket
side, and a pointer to a `_VkInstance` happens on the C side.
Taking it from the top:
Wow! Thank you for the detailed response, and the saintly patience behind it.
In following your email, this is the working result after using '_pointer' in
the function signature:
(define instance-ptr (malloc _VkInstance))
(vkCreateInstance instcreateinfo #f instance-ptr)
I’ve updated the game jam description to add:
- Full games, game components or tools are all acceptable entries. e.g.
tile editor, game map editor, procedural content generator, etc.

Sorry, this was my mistake (edited the wrong configuration and broke

I would use a really simple OpenGL draw call that just draws a
rectangle and update the texture contents with the screen bits.

I decided to write a computer simulator (16-bit machine as the one
built in nand2tetris course) in Racket. The computer maps the screen
to a memory space where bits represent the pixel colors (black and
