Código de exemplo para criar um grupo local

O exemplo de código C++ a seguir cria um grupo local em um servidor membro ou em um computador em execução na Estação de Trabalho do Windows NT ou no Windows 2000 Professional.

/********************************************************************

    CreateMachineLocalGroup()

    Creates a local group on the specified computer and adds the 
    specified objects to the group.

    Parameters:

    pwszComputer - A null-terminated string that contains the name  
    of the computer on which to create the local group.

    pwszGroupName - A null-terminated string that contains the name  
    of the group to create.

    rgpwszObjectsToAdd - Contains an array of null-terminated strings 
    that specify the objects to add to the new group. The objects in  
    this array must belong to the computer specified in pwszComputer.  
    dwObjectsToAdd contains the number of elements in this array. 
    This parameter is ignored if dwObjectsToAdd contains zero.

    dwObjectsToAdd - Contains the number of elements in the 
    rgpwszObjectsToAdd array. Pass zero for this parameter to not
    add any objects to the group.
