have a requirement to copy files from my Mac OS app. I find: success=[NSWorkSpace performFileOperation:NSWorkSpaceCopyOperation source:nsstring* // source directory path destination:nsstring* // target directory path file:nsarray* // nsstring array containing short paths of files or directories tag:nsinteger* // on return, <0 on failure, 0 if sync finish, >0 if async ] My question relates to asynchronousness (is that a word)? It looks like a synchronous method as it returns a success or failure. But the documentation says of the tag variable "a positive integer if the operation was performed asynchronously. If the value is a positive integer, the value is a tag that identifies the requested file operation." This confuses me. The examples I've seen don't do anything special with the tag.
I may be just missing a document giving a context to this... Its in the past tense. If it said "has been started asynchronously" of course I would be looking for a method to wait for completion. So what does "was performed asychronously" mean? Do I need to care? In what sense was it asynchronous if my API is waiting for completion? What is the requested file operation identifier and what API might I use it with? Do I need to release it?
