+// Overview:
+// Test static data in DLLs
+// API Information:

+// Details:
+// - Test statically linked DLLs with static data and verify results.
+// - Load a dynamically loadable DLL, check DLL data, verify results.
+// - Load a dynamically loadable DLL in another thread, check DLL data, 
+// verify results.
+// - Load a DLL that is statically linked to the test process, check 
+// DLL data, verify results.
+// - Load in a different thread a DLL that is statically linked to the 
+// test process, check DLL data, verify results.
