iOS Memory management of structs

Most discussion about memory management of Objective-C is based on classes derived from NSObject. How about the memory management of a struct? Is it similar to standard C++ memory management (using new and delete)? An example struct is shown as follows:

Code:

typedef struct
{
    int startPosition;
    int endPosition;
    int Velocity;
} carInfo;

Click to expand...

struct carInfo *car = malloc(sizeof(struct carInfo));

free(car);
car = NULL;

struct carInfo car;

Could I pass parameter like this?

Code:

struct carInfo *car = malloc(sizeof(struct carInfo));
[self changeData: car];
NSLog([NSString stringWithFormat:@"Car start position: %d", car->startPosition]);


-(void) changeData: (carInfo*) myData
{   myData->startPosition = 100;    }

Click to expand...

-(void) changeData: (struct carInfo*) myData

struct carStruct
{
    int startPosition;
    int endPosition;
    int Velocity;
};

typedef struct carStruct carInfo;
