This function associates a pointer-conversion procedure with a window.
Syntax
WinSetWindowThunkProc(hwnd, pthunkpr)
Parameters
- hwnd (HWND) - input
- Window handle.
- pthunkpr (PFN) - input
- Pointer-conversion procedure identifier.
- NULL
- Any existing pointer-conversion procedure is dissociated from this window.
- Other
- The pointer-conversion procedure to be associated with this window.
Returns
- rc (BOOL) - returns
- Success indicator.
- TRUE
- Successful completion
- FALSE
- An error occurred.
Example Code
In this example, any thunking procedure is dissociated from the window.
#define INCL_WINTHUNKAPI #include <os2.h> HWND hwnd; WinSetWindowThunkProc(hwnd, NULL);
Definition
#define INCL_WINTHUNKAPI /* Or use INCL_WIN, INCL_PM, */ #include <os2.h> HWND hwnd; /* Window handle. */ PFN pthunkpr; /* Pointer-conversion procedure identifier. */ BOOL rc; /* Success indicator. */ rc = WinSetWindowThunkProc(hwnd, pthunkpr);
