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
Vt CLIENT
handle.
The
cl_auth
field of the
Vt CLIENT
structure should be initialized by the
Vt 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
Fn auth_destroy
A function macro that destroys the authentication
information associated with
Fa auth .
Destruction usually involves deallocation
of private data structures.
The use of
Fa auth
is undefined after calling
auth_destroy (.);
Fn 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.
Fn authsys_create
Create and return an RPC authentication handle that contains
AUTH_SYS
authentication information.
The
Fa host
argument
is the name of the machine on which the information was
created;
Fa uid
is the user's user ID;
Fa gid
is the user's current group ID;
Fa len
and
Fa aup_gids
refer to a counted array of groups to which the user belongs.
Fn authsys_create_default
Call
authsys_create ();
with the appropriate arguments.
