The Win32 Network Management APIs 12

 

 

 

 

Another Get User Information Program Example

 

The following code sample demonstrates how to retrieve information about a particular user account with a call to the NetUserGetInfo() function. The sample calls NetUserGetInfo(), specifying various information levels . If the call succeeds, the code prints information about the user account. Finally, the sample frees the memory allocated for the information buffer.

Create a new empty Win32 console application project. Give the project name and change the project location is needed.

Then, add the source file. Give it a name.

Then, add the following source code.

 

#include <windows.h>

#include <stdio.h>

#include <assert.h>

#include <lm.h>

/* for ConvertSidToStringSid function */

#include <sddl.h>
