DESCRIPTION

MAP FUNCTIONS

struct map* map_init(void)

Allocates and returns a new string map. String maps only support string values.

struct map* map_init_void(void)

Allocates and returns a new void map. A void map supports values of any type.

void map_free(struct map* map)

Frees the provided map and all it's keys. Values are only freed if it is a string map.

bool map_put(struct map* map, const char* key, char* value)

Returns true if the given map is a string map, otherwise returns false and prints a message to stderr.

struct map* map - The map to insert into.

const char* key - The key to store the value under. This key is given to strdup() before being saved and will be freed when running map_free().

char* value - The value to store. This value is given to strdup() before being saved and will be freed when running map_free(). If the value is NULL it will not be given to strdup().

bool map_put_void(struct map* map, const char* key, void* value)

Returns true if the given map is a void map, otherwise returns false and prints a message to stderr.

struct map* map - The map to insert into.

const char* key - The key to store the value under. This key is given to strdup() before being saved and will be freed when running map_free().

void* value - The value to store. This pointer is stored in the map, it is on the caller to free this and it will not be freed when running map_free().

void* map_get(struct map* map, const char* key)

Returns the value stored under key or NULL if no key exists. NULL can also be returned if it was stored there with map_put() or map_put_void().

struct map* map - The map to get the value from.

const char* key - The key to lookup.

bool map_contains(struct map* map, const char* key)

Returns true if the key exists, false otherwise. This is implemented as a value != NULL check so a NULL value is considered to not exist.

struct map* map - The map to check against.

const char* key - The key to check for.

size_t map_size(struct map* map)

Returns the number of entries in this map.

struct map* map - The map to get the size of.
