- Thread-topic: Interrupt copyItemAtPath
I have verified that the waiting loop
while(!gFileCopiedDone && !mUserPressedStop){
CFRunLoopRunInMode(kCFRunLoopDefaultMode, 5.0, true);
}
slows down the copy speed 3 times and more. I can't use that.
I have to copy a hierarchical list of files, and let the user make his
choice if a problem occurs during the copy of each file.
Is a different way to get a value returned at each file copied?
Something like
if(stage == kFSOperationStageComplete){
go and copy the next file
}
would make me redesign all of my code...
So it doesn't sound as the best solution for me.
