Wraps the portalocker recipe for easy usage
Project description
Overview
Portalocker is a library to provide an easy API to file locking.
Originally created as a Python Recipe by Jonathan Feinberg and Lowell Alleman http://code.activestate.com/recipes/65203-portalocker-cross-platform-posixnt-api-for-flock-s/
Examples
To lock a file exclusively, use the lock method:
>>> import portalocker
>>> file = open("somefile", "r+")
>>> portalocker.lock(file, portalocker.LOCK_EX)
>>> file.seek(12)
>>> file.write("foo")
>>> file.close()
There is no explicit need to unlock the file as it is automatically unlocked after file.close(). If you still feel the need to manually unlock a file than you can do it like this:
>>> portalocker.unlock(file)
Do note that your data might still be in a buffer so it is possible that your data is not available until you flush() or close().
