Functions

Function	Description
Storage_DeleteMutableFile	Deletes the mutable storage file for the application.
Storage_GetAbsolutePathInImagePackage	Gets a null-terminated string that contains the absolute path to a location within the image package of the running application, given a relative path inside the image package.
Storage_OpenFileInImagePackage	Takes a relative path inside the image package and returns an opened read-only file descriptor.
Storage_OpenMutableFile	Retrieves a file descriptor to the mutable storage file for the application. If the application doesn't already have a mutable storage file, this function creates a file and then returns the file descriptor.
