# [MS-DRSR] Directory Replication Service (DRS) DRSUAPI Interface implementation 

# 

# Best way to learn how to use these calls is to grab the protocol standard 

# so you understand what the call does, and then read the test case located 

# at https://github.com/SecureAuthCorp/impacket/tree/master/tests/SMB_RPC 

# 

# Some calls have helper functions, which makes it even easier to use. 

# They are located at the end of this file.  

# Helper functions start with "h"<name of the call>. 

# There are test cases for them too.
