- struct MmapAllocator;
- Allocator (currently defined only for Posix and Windows) using mmap and munmap directly (or their Windows equivalents). There is no additional structure: each call to allocate(s) issues a call to mmap(null, s, PROT_READ | PROT_WRITE, MAP_PRIVATE | MAP_ANONYMOUS, -1, 0), and each call to deallocate(b) issues munmap(b.ptr, b.length). So MmapAllocator is usually intended for allocating large chunks to be managed by fine-granular allocators.
- static shared MmapAllocator instance;
- The one shared instance.
- enum size_t alignment;
- Alignment is page-size and hardcoded to 4096 (even though on certain systems it could be larger).
- shared void allocate(size_t bytes);
shared bool deallocate(void b);
- Allocator API.
