Hello,

was this API EnumDisplayMonitors always crashing into oblivion when called with invalid combination of params like

Code: Select all

EnumDisplayMonitors(0, 0, 0, 0);

or its new feature since Vista?

Expected result: the function fails and return zero.
Observed result: crash


Thanks.

Funny, there is not sanity check for the pointer of the callback function at all. Windows XP is also affected, probably nothing was done since its implementation in Windows 2000.

Thanks for checking. I'm checking win32k, so far fun bsods generated and only this routine crashing so annoying during test.
