Retrieving the User Name

  • Article

To retrieve the name of the user associated either with a local device connected to a network resource or with the name of a network, an application can call the WNetGetUser function.

The following example uses the device name to retrieve the name of the user. The sample calls an application-defined error handler to process errors, and the TextOut function for printing.

CHAR szUserName[80]; 
DWORD dwResult, cchBuff = 80; 
 
// Call the WNetGetUser function.
//
dwResult = WNetGetUser("z:", 
    (LPSTR) szUserName, 
    &cchBuff); 
 
// If the call succeeds, print the user name.
//
if(dwResult == NO_ERROR) 
    printf("User name: %s\n", szUserName); 
 
// Handle the error.
//
else 
{ 
    printf("WNetGetUser failed.\n"); 
}
