Q: What’s wrong with this code?
NSLock* arrayLock = GetArrayLock();
NSMutableArray* myArray = GetSharedArray();
id anObject;
[arrayLock lock];
anObject = [myArray objectAtIndex:0];
[arrayLock unlock];

description of mixing pointer and array syntax
View gist:e4f2ce9694d3b28a751c
[18:15:43] <Chris> Norrin: it's, like all C declarations, "declaration follows use".
[18:16:14] <Chris> So consider char (*x)[42]; You can then reason that *x is a char[42]. And (*x)[3] is a char.
[18:16:46] <Chris> Norrin: and in the case of char *x[42]; you can say that x[3] is a char * and *x[3] is a char.
so [] has precedence over *. hence why the () are required depending on intention.
[18:14:32] <Chris> Norrin: char *(*a)[42]; is a pointer to array of 42 char pointers.

You can’t perform that action at this time.
