+To minimize the possibility of data corruption when exporting a class with [__declspec(dllexport)](../../cpp/dllexport-dllimport.md), make sure that:
 
 - All your static data is accessed through functions that are exported from the DLL.
 
 - No inlined methods of your class can modify static data.
 
-- No inlined methods of your class use CRT functions or other library functions use static data.
+- No inlined methods of your class use CRT functions or other library functions that use static data.

+- No inlined class functions use CRT functions, or other library functions, where you access static data.
 
 - No methods of your class (regardless of inlining) can use types where the instantiation in the EXE and DLL have static data differences.
 
 You can avoid exporting classes by defining a DLL that defines a class with virtual functions, and functions you can call to instantiate and delete objects of the type.  You can then just call virtual functions on the type.
