Data Structures
struct	pmap_entry
	A key, value pair. More...

Macros
#define	pmap_get(type, map, key)   ((type*)pmap_get(map, key))
	Returns the value of "key".
#define	foreach_pmap(pmap, curr)   for (curr = pmap_first(pmap); curr; curr = pmap_next(pmap))
	Iterate over all elements in the map setting curr to the current element.

Typedefs
typedef struct pmap	pmap
	A map which maps addresses to addresses.

Functions
pmap *	pmap_create (void)
	Creates a new empty map.
pmap *	pmap_create_ex (size_t slots)
	Creates a new empty map with an initial number of slots.
void	pmap_destroy (pmap *)
	Deletes a map.
void	pmap_insert (pmap *map, const void *key, void *value)
	Inserts a pair (key,value) into the map.
int	pmap_contains (pmap *map, const void *key)
	Checks if an entry with key "key" exists.
pmap_entry *	pmap_find (pmap *map, const void *key)
	Returns the key, value pair of "key".
void *	pmap_get (pmap *map, const void *key)

size_t	pmap_count (pmap *map)
	Return number of elements in the map.
pmap_entry *	pmap_first (pmap *map)
	Returns the first entry of a map if the map is not empty.
pmap_entry *	pmap_next (pmap *)
	Returns the next entry of a map or NULL if all entries were visited.
