HANDLE BeginDeferWindowPos(nNumWindows)
This function allocates memory to contain a multiple window-position data structure and returns a handle to the structure. The DeferWindowPos function fills this data structure with information about the target position for a window that is about to be moved. The EndDeferWindowPos function accepts this data structure and instantaneously repositions the windows using the information stored in the structure.
| Parameter | Type/Description |
| nNumWindows | int Specifies the initial number of windows for which position information is to be stored in the data structure. The Defer-WindowPos function increases the size of the structure if needed. |
The return value identifies the multiple window-position data structure. The return value is NULL if system resources are not available to allocate the structure.
