Use the debugger to look at the values of the relevant variables, especially dataSize. Since the result is a crash instead of an exception, the NSRange you create is valid; so I assume it’s just larger than your buffer so the copy runs off the end into unmapped address space. Also, what exactly is the type of ‘bytes’? If it’s a pointer to a malloced buffer, you shouldn’t be passing its address, rather its value, otherwise you’re going to copy into the stack and blow up. —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
