#define INCL_WINWINDOWMGR
 
BOOL WinSetWindowPtr(hwnd, index, p)
HWND hwnd;      /* handle of the window                  */
SHORT index;    /* index of the reserved memory          */
PVOID p;        /* pointer to place into reserved memory */
 
The WinSetWindowPtr function places a pointer value into the reserved memory
of a window.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hwnd       Identifies the window whose reserved memory will be changed.
 
index      Specifies the zero-based index of the pointer value to set. Valid
           values are in the range zero through the number of bytes of
           window data (for example, a value of 8 would be an index to the
           third pointer). The value QWP_PFNWP can be used as the index for
           the address of the window procedure for the window.
 
p          Specifies the pointer to store in the window's reserved memory.
 
Return Value
 
The return value is TRUE if the function is successful or FALSE if an error
occurs.
