13 When using multi-threaded applications, it is often required to access or
14 modify memory which is shared between threads. Atomic integer and pointer
15 operations are an efficient way to handle this issue (another, less efficient,
16 way is to use a wxMutex or wxCriticalSection). A native implementation exists
17 for Windows, Linux, Solaris and Mac OS X; for others, a wxCriticalSection is
18 used to protect the data.
19
20 One particular application is reference counting (used by so-called
21 @ref group_class_smartpointers "smart pointers").
22
23 You should define your variable with the type wxAtomicInt in order to apply
24 atomic operations to it.
