What is winreg.FlushKey(key) in Python?

winreg (Windows Registry API) provides functions to expose the Windows Registry API to Python. We use this module to expose a low-level interface to the registry.

Flushkey

The method winreg.FlushKey writes all the attributes of any specified key to the Windows registry. This method returns when all the contents have been written to the disk.

Do not use a Flushkey() call unless you are certain that it is required. Do not use this method for changing key, as the Flushkey() method returns only after the complete data has been written to the registry.

Syntax

winreg.FlushKey(key)

Parameters

key: This refers to the key whose attributes are written into the registry. Any openA key that has already been opened by the user HKEY_* constant or one of the predefined HKEY_* constants can be given as a parameter to the method.

Code

This function calls the winreg.FlushKey using self.hkey (one of the open keys) as one of the parameters.

def flush(self):
       _winreg.FlushKey(self.hkey)
