Re: [GD-Windows] GetDIBits() return values

[Dan T. <da...@ar...>]

Any possibility of threading issues?

If you add a second call to GetDIBits right after (i.e. on skitzo fail, 
try agian), does it work or fail again? Maybe toss a Sleep(1) between 
the two?

If the second one fails, you might be able to disasm into gdi and see 
whats up. Could try VirtualAllocing the memory and protect it vs Write 
on the second call, see if it even touches the memory.

All I got.
