Function Documentation

BOOL AdCheckDirectory	(	NSString *	directoryPath,
		NSError **	error
	)

Returns YES if a directory exists at directoryPath. If it doesn't returns NO and sets error if its provided.

BOOL AdCreateParallelSharedDirectory	(	NSString *	directoryPath,
		NSError **	error
	)

Function for creating a single directory that will be used by all nodes in a parallel process. It ensures that no node exits the function before the directory is accesible by them.

In a parallel environment, where process access a shared filesystem, a directory creation even on one node can take time to propogate to other nodes. If this situation isn't accounted for then a node may attempt to write to a directory that doesn't exist yet.

In serial this method does nothing and always returns NO.
