Data Structures
struct	stack_pointer_t
	Structure to define a stack in memory. More...

Macros
#define	STACK_POINTER_GUARD_PAGES   1
	The amount of guard pages to use for stacks.

Functions
uint64_t	stack_pointer_init (stack_pointer_t *stack, uintptr_t maxAddress, uint64_t maxPages)
	Initializes a stack pointer structure, does not allocate or map any memory.
uint64_t	stack_pointer_init_buffer (stack_pointer_t *stack, void *buffer, uint64_t pages)
	Initializes a stack pointer structure using a provided buffer, does not allocate or map any memory.
void	stack_pointer_deinit (stack_pointer_t *stack, thread_t *thread)
	Deinitializes a stack pointer structure and unmaps any mapped memory.
void	stack_pointer_deinit_buffer (stack_pointer_t *stack)
	Deinitializes a stack pointer structure that was initialized using stack_pointer_init_buffer().
bool	stack_pointer_is_in_stack (stack_pointer_t *stack, uintptr_t addr, uint64_t length)
	Check if an region is within the stack.
bool	stack_pointer_overlaps_guard (stack_pointer_t *stack, uintptr_t addr, uint64_t length)
	Check if an region overlaps the guard.
