The method copies into aBuffer all the objects in the receiver; the size of the buffer must therefore be at least the count of the receiver multiplied by the size of an object reference, as shown in the following example (note that this is just an example, you should typically not create a buffer simply to iterate over the contents of an array):

NSArray *mArray = // ...;

id *objects;

NSUInteger count = [mArray count];

objects = malloc(sizeof(id) * count);

[mArray getObjects:objects];

for (i = 0; i < count; i++) {

    NSLog(@"object at index %d: %@", i, objects[i]);

}

free(objects);
