Flush a pipe associated to an NSFileHandle

Question

I am reading piped output from a console application via an NSFileHandle in Cocoa. How can I flush the stream associated to that file handle. If I could get a FILE* object from the NSFileHandle I could call fflush(). Is there a way around this?

You could try `fdopen()` followed by `fflush()` but I’m not sure pipes need to be flushed. — , Sep 23 '11 at 18:06

I believe the equivalent in NSFileHandle is -synchronizeFile.

This results in an operation-not-supported exception if the underlying file handle is an NSPipe. – Eric apRhys Mar 29 '15 at 02:02
@EricapRhys is there an alternative solution to `synchronizeFile` for this case? – Aaron Ash Oct 05 '16 at 14:21
