Apple AppleShare 3.0 Users and Groups Programming Interface - Manual (Page 9)

UGNewUser creates a new user. The pointer ugNamePtr (a pointer to a Str31)
contains the name of the user and the pointer ugPassword (a pointer to a
Str8) contains the password. The new user is created with the characteristics
passed in ugUserFlags (a long; see "Data Structures," later in this document,
for details). To create the administrator user, set ugUserID to 1. To create
a regular user, set ugUserID to 0. The user ID of the user created is passed
back in ugUserID.
