Define Labyrinth Void Allocpagegfpatomic Exclusive Access

allocpage is a non-standard allocation function. Unlike malloc (bytes) or mmap (virtual memory), allocpage deals with physical or virtual memory pages (usually 4KB, 2MB, or 1GB). The absence of a size parameter implies the page size is fixed globally.

In the Labyrinth allocator, each page is a "room" in the maze. allocpage navigates the labyrinth to find a free room. define labyrinth void allocpagegfpatomic exclusive

labyrinth is not a standard C type (int, void*, size_t). In this context, it could be: allocpage is a non-standard allocation function

For a definition, we posit:

typedef struct labyrinth 
    void *entrance;          // base address of first page block
    struct labyrinth_room **rooms; // indirect index of free pages
    atomic_uint_least64_t version; // for atomic exclusivity
 labyrinth_t;

The keyword define labyrinth void allocpagegfpatomic exclusive is not a valid C statement, but it is a powerful specification. It defines a set of constraints: labyrinth is not a standard C type (
