This callback can be used to free any memory allocated in PAINTCALLBACK_PREPAINT.
Handle of the device context passed to the paint function.
Pointer to the bitmap handle structure holding the input data.
Void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of the PAINTCALLBACKDATA structure.)
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
pDisplay is the pDisplay member from the PAINTCALLBACKDATA structure that you passed to the paint function. The default callbacks expect it to be a HDC handle. But, if you override all the paint callbacks, it can be a pointer of any type you want.
This callback is called after all other paint callbacks. This callback will be called exactly once for a paint operation.
You can use this callback to perform any device un-initialization or free any memory allocated in the PAINTCALLBACK_PREPAINT callback.
