[hatari-devel] missing SDL_Lock in png snapshot ?

[npomarede at corp.free.fr]

Hello,

looking at the png screenshot's code, I see a call to SDL_UnlockSurface 
after processing each row, but I don't see the corresponding 
SDL_LockSurface.

Am I missing something or is this really an (harmless) error ? Why is a 
lock required for each row, would it be enough to lock at start and unlock 
when whole screen was saved as png ?

Eero, any idea ? (I think you're the one who wrote png support)
