typedef struct s_bunny_stack
{
const size_t length;
const void * const * const top;

} t‌_‌b‌u‌n‌n‌y‌_‌s‌t‌a‌c‌k;

Description

This structure is the main data of the Stack container.

This type cannot be declared on stack. It must be created by a call to b‌u‌n‌n‌y‌_‌n‌e‌w‌_‌s‌t‌a‌c‌k.

Attributes

const size_t length:
The amount of elements in the Stack container.
const void * const * const * top:
A pointer to a node containing the first element of the Stack container, and the address of its following element if there is one. This attribute is NULL if there is no element inside the Stack.

INDEX

typedef struct s_bunny_stack_node
{
void *data;
struct s_bunny_stack_node *next;

} t‌_‌b‌u‌n‌n‌y‌_‌s‌t‌a‌c‌k‌_‌n‌o‌d‌e;

Description

This structure is the node in which every single data is referenced inside the stack.

Attributes

void *data:
A pointer to a stored data.
struct s_bunny_stack_node *next:
The node following the current one or NULL if there is none.
This type is an inside type of the Stack module and should not be created by you.
