Functions
void	MapOfStrings_Initialize (MapOfStrings *map)
	Initialize the given MapOfStrings structure so it is ready for use.
void	MapOfStrings_Clear (MapOfStrings *map)
	Clear the given MapOfStrings object, releasing all memory associated with it. Leaves the object in an initialize state to be reused, if desired.
bool	MapOfStrings_AddStringList (MapOfStrings *map, const char *key, ConstStringList *value)
	Add a key/value association to the given MapOfStrings object. The MapOfStrings object takes ownership of the key and value arguments and will free them when MapOfStrings_Clear() is called in the object.
bool	MapOfStrings_AddArray (MapOfStrings *map, const char *key, const char **value)
	Add a key/value association to the given MapOfStrings object, where the value is provided as a NULL-terminated array of string pointer. This array is copied into a StringList object for storage in the map.
int	MapOfStrings_Find (MapOfStrings *map, const char *key)
	Find the specified key in the given MapOfStrings object, returning an index into the object.

Function Documentation

MapOfStrings_AddArray()

bool MapOfStrings_AddArray	(	MapOfStrings *	map,
		const char *	key,
		const char **	value
	)

Add a key/value association to the given MapOfStrings object, where the value is provided as a NULL-terminated array of string pointer. This array is copied into a StringList object for storage in the map.

Parameters

map	The MapOfStrings object to add to.
key	The key value to be added. This must be allocated, directly or indirectly, with malloc() as it will be freed when the MapOfStrings object is cleared.
value	An array of string pointers terminated by a NULL pointer.

Returns

Returns true if the key/value was successfully added; otherwise, returns false, indicating an out of memory condition (or NULL argument).

MapOfStrings_AddStringList()

bool MapOfStrings_AddStringList	(	MapOfStrings *	map,
		const char *	key,
		ConstStringList *	value
	)

Add a key/value association to the given MapOfStrings object. The MapOfStrings object takes ownership of the key and value arguments and will free them when MapOfStrings_Clear() is called in the object.

Parameters

map	The MapOfStrings object to add to.
key	The key value to be added. This must be allocated, directly or indirectly, with malloc() as it will be freed when the MapOfStrings object is cleared.
value	The ConstStringList object to add as the value. This must be allocated with malloc() as it will be freed when the MapOfStrings object is cleared.

Returns

Returns true if the key/value was successfully added; otherwise, returns false, indicating an out of memory condition (or NULL argument).

MapOfStrings_Clear()

void MapOfStrings_Clear

(

MapOfStrings *

map

)

Clear the given MapOfStrings object, releasing all memory associated with it. Leaves the object in an initialize state to be reused, if desired.

Parameters

map	The MapOfStrings object to clear.

MapOfStrings_Find()

int MapOfStrings_Find	(	MapOfStrings *	map,
		const char *	key
	)

Find the specified key in the given MapOfStrings object, returning an index into the object.

Parameters

map	The MapOfStrings object to search.
key	The key to search for.

Returns

Returns the index of the found item if successful; otherwise, returns -1, indicating the key was not found.

MapOfStrings_Initialize()

void MapOfStrings_Initialize

(

MapOfStrings *

map

)

Initialize the given MapOfStrings structure so it is ready for use.

Alternatively, declare the MapOfStrings instance like this:

MapOfStrings map = { 0 };

Parameters

map	The MapOfStrings object to initialize.
