PRB: WNetGetUser Does Not Fail on Win95

SYMPTOMS

WNetGetUser always succeeds on Windows 95, no matter what value you include for the lpName parameter. As long as you pass a valid pointer to the string, the function will succeed and will set the lpUserName parameter to the name of the person that logged into the system.

For instance if you call:

   res = WNetGetUser("VERYBADPATHDESCRIPTION", szName, cbName)
				

The function will return NO_ERROR (Zero) indicating that it was successful, even though there is no drive letter or other path, and the szName parameter will receive the user's logged in name.

According to the documentation the function should return one of two other errors:

 // Link with MPR.LIB

   #include <windows.h>
   #include <stdio.h>
   #include <winnetwk.h>

   void main(int argc, char *argv[])
   {
      TCHAR szName[50];
      DWORD cbName = 50;
      int res;

      if((res = WNetGetUser(argv[1], szName, &cbName)) == NO_ERROR)
         printf("UserName:\t%s\n", szName);
      else
         printf("Error: %d\n", res);
      return;
   }
