Does NSValue free its value when freed?

Question

Have a look at this pseudocode:

void* magicpointer = malloc(OVER_NINE_THOUSAND);
NSValue* v = [NSValue valueWithPointer:magicpointer];
[v release];

When v is released, does magicpointer get freed as well, or do I have to do that manually? I am using manual reference counting.

Answer 1

It doesn't get freed - NSValue is just a wrapper so you can treat arbitrary values as objects. It doesn't do anything with the wrapped pointer.

Answer 2

No, NSValue won't.

Sounds like you might want to use NSData, it can free it's pointer when it's released:

    void* magicpointer = malloc(OVER_NINE_THOUSAND);
    NSData *d = [NSData dataWithBytesNoCopy:magicpointer
                                     length:OVER_NINE_THOUSAND
                               freeWhenDone:YES];
    //d is autoreleased, so no need to -release it.
