Example Requirements

When compiling the C/C++ examples, include the following in your project:

The following macros are used in all of the LEAD WIC-Enabled C/C++ Codec samples. When testing the files, include these macros in a common header file.

                    #define IFS(fn)                 \
                    {                               \
                        if (SUCCEEDED(hr))          \
                        {                           \
                            hr = (fn);              \
                        }                           \
                    }
            
                    #define RELEASE_INTERFACE(pi)   \
                    {                               \
                        if (pi)                     \
                        {                           \
                            pi->Release();          \
                            pi = NULL;              \
                        }                           \
                    }
            
                    #define DELETE_POINTER(p)       \
                    {                               \
                        if (p)                      \
                        {                           \
                            delete p;               \
                            p = NULL;               \
                        }                           \
                    }

Include the following header file in your C/C++ examples project.The examples use this CString imlementation.
```
                    #include <atlstr.h>
                    
```
