poll_file
poll_file(path, interval_s::Real, timeout_s::Real) -> (previous::StatStruct, current::StatStruct)
Monitor a file for changes by polling every interval_s
seconds until a change occurs or timeout_s
seconds have elapsed. The interval_s
should be a long period; the default is 5.007 seconds.
Returns a pair of StatStruct
objects (previous, current)
when a change is detected.
To determine when a file was modified, compare mtime(prev) != mtime(current)
to detect notification of changes. However, using watch_file
for this operation is preferred, since it is more reliable and efficient, although in some situations it may not be available.
