- // BOOL AppProfileWriteBytes
- //
- // Description:
- // This function writes a raw structure of bytes to the application's
- // ini section that can later be retrieved using AppProfileReadBytes.
- // This gives an application the ability to write any structure to
- // the ini file and restore it later--very useful.

- // NOTE! Starting with Windows for Workgroups 3.1 there are two new
- // profile functions that provide the same functionality of this
- // function. Specifically, these functions are GetPrivateProfileStruct
- // and WritePrivateProfileStruct. These new functions are provided
- // by the Common Controls DLL. The prototypes are as follows:
- //
- // BOOL GetPrivateProfileStruct
- // (
- // LPSTR szSection,
- // LPSTR szKey,
- // LPBYTE lpStruct,
- // UINT uSizeStruct,
- // LPSTR szFile

- // (

- // LPBYTE lpStruct,
- // UINT uSizeStruct,

- //
- // If you are building an application that is for Window for Workgroups
- // or newer versions of Windows, you will probably want to use the
