+    Macro to be used for thread-specific variables declarations.
+
+    This macro can be used to define thread-specific variables of the specified
+    @a type. Such variables must be global or static. Example of use:
+    @code
+    struct PerThreadData
+    {
+        ... data which will be different for every thread ...
+    };
+
+    static wxTLS_TYPE(PerThreadData *) s_threadPtr;
+    @endcode
+
+    Currently only types of size less than size of a pointer are supported.
+    This limitation will be lifted in the future.
