DESCRIPTION
These routines are part of the RPC library that allows C language programs to
make procedure calls on other machines across the network, with desired
authentication.
These routines are normally called after creating the
CLIENT
handle. The
cl_auth field
of the
CLIENT
structure should be initialized by the
AUTH
structure returned by some of the following
routines. The client's authentication information is passed to the server when
the RPC call is made.
Only the
NULL
and the
SYS
style
of authentication is discussed here.
ROUTINES
-
-
- auth_destroy()
- A function macro that destroys the authentication
information associated with auth. Destruction
usually involves deallocation of private data structures. The use of
auth() is undefined after calling
auth_destroy().
-
-
- authnone_create()
- Create and return an RPC authentication handle that passes
nonusable authentication information with each remote procedure call. This
is the default authentication used by RPC.
-
-
- authsys_create()
- Create and return an RPC authentication handle that
contains
AUTH_SYS
authentication information. The
parameter host is the name of the machine on which
the information was created; uid is the user's user
ID; gid is the user's current group ID;
len and aup_gids refer to a
counted array of groups to which the user belongs.
-
-
- authsys_create_default()
- Call authsys_create() with the
appropriate parameters.
