- hWnd
Identifies the window and, indirectly, the class to which the window belongs.
- nIndex
Specifies the zero-based byte offset of the value to be retrieved. Valid values are in the range zero through the number of bytes of extra window memory, minus two; for example, if you specified 10 or more bytes of extra window memory, a value of 8 would be an index to the fifth 16-bit integer. |
If the function succeeds, the return value is the requested 16-bit value.
If the function fails, the return value is zero. To get extended error information, call GetLastError. |
