Functions
void	MapOfInt_Initialize (MapOfInt *map)
	Initialize the given MapOfInt structure so it is ready for use.
void	MapOfInt_Clear (MapOfInt *map)
	Clear the given MapOfInt object, releasing all memory associated with it. Leaves the object in an initialize state to be reused, if desired.
bool	MapOfInt_Add (MapOfInt *map, const char *key, int value)
	Add a key/value association to the given MapOfInt object. The MapOfInt object takes ownership of the key and value arguments and will free them when MapOfInt_Clear() is called in the object.
int	MapOfInt_Find (MapOfInt *map, const char *key)
	Find the specified key in the given MapOfInt object, returning an index into the object.

Function Documentation

MapOfInt_Add()

bool MapOfInt_Add	(	MapOfInt *	map,
		const char *	key,
		int	value
	)

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

Parameters

map	The MapOfInt 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 MapOfInt object is cleared.
value	The integer being mapped to the key.

Returns

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

MapOfInt_Clear()

void MapOfInt_Clear

(

MapOfInt *

map

)

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

Parameters

map	The MapOfInt object to clear.

MapOfInt_Find()

int MapOfInt_Find	(	MapOfInt *	map,
		const char *	key
	)

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

Parameters

map	The MapOfInt 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.

MapOfInt_Initialize()

void MapOfInt_Initialize

(

MapOfInt *

map

)

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

Alternatively, declare the MapOfInt instance like this:

MapOfInt map = { 0 };

Parameters

map	The MapOfInt object to initialize.
