This case ampersand in C++ means a reference to a variable. In C it behaves like a pointer.
But be careful: a reference is not a pointer in C++ (don't say something like that on stackoverflow or you'll get strongly and continuosly downvoted  ;D ;D ;D ;D ;D People don't read the contest just outline the first thing seemingly strange at them  ;D ;D ;D ;D)
The code is to be translated as:

Code: [Select]

DetourDetach(&TrueMessageBoxA, MyMessageBoxA);
