Classes
struct	BigResourceList
	Represents an expandable list of pointers to BigResource objects. Use the BigResourceList_Clear() to free up the resources in the list. Use the BigResourceList_AddResource() to add a BigResource object to the list (and also take ownership of the BigResource object). More...

Functions
static void	BigResourceList_Clear (BigResourceList *resourceList)
	Clear the given BigResourceList object by freeing up all allocated BigResource objects and resetting the list to a "new" state so it can be reused.

static int	BigResourceList_AddResource (BigResourceList resourceList, BigResource resource)
	Add a BigResource object to the given BigResourceList object. The list takes ownership of the BigResource object and is responsible for releasing all memory associated with it.

void	BigResourceManager_Clear (void)
	Release all resources owned by the Big Resource Manager.

int	BigResourceManager_AddResource (BigResource *rawResource)
	Add a new big resource and return the ID of the resource. If the resource is successfully added, the Big Resource Manager owns the resource and will free it on exit.

BigResource *	BigResourceManager_GetResource (int bigResourceId)
	Retrieve the requested big resource.

Variables
static BigResourceList	_resources = { 0 }
	A list of BigResource objects. Initialized by a call to the BigResourceList_AddResource(). This is used by the BigResourceManager_GetResource() to retrieve a BigResource object.

Function Documentation

◆ BigResourceList_AddResource()

static int BigResourceList_AddResource	(	BigResourceList *	resourceList,
		BigResource *	resource
	)

static

Add a BigResource object to the given BigResourceList object. The list takes ownership of the BigResource object and is responsible for releasing all memory associated with it.

This is called from the BigResourceManager_AddResource() function.

Parameters

resourceList	The BigResourceList object to add to.
resource	The BigResource object to add to the BigResourceList.

Returns: Returns the index of the image added if successful; otherwise, returns -1 to indicate an error (typically an out of memory problem).

◆ BigResourceList_Clear()

static void BigResourceList_Clear ( BigResourceList * resourceList )

static

Clear the given BigResourceList object by freeing up all allocated BigResource objects and resetting the list to a "new" state so it can be reused.

This is called from the BigResourceManager_Clear() function.

Parameters

resourceList A pointer to the BigResourceList to be cleared.

◆ BigResourceManager_AddResource()

int BigResourceManager_AddResource ( BigResource * rawResource )

Add a new big resource and return the ID of the resource. If the resource is successfully added, the Big Resource Manager owns the resource and will free it on exit.

Parameters

rawResource The BigResource object to add.

Returns: Returns the handle to the new big resource added to the manager. Returns -1 if something went wrong (typically an out of memory condition).
