.Sh 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.
|
|
.Pp
|
|
These routines are normally called after creating the
|
|
.Vt CLIENT
|
|
handle.
|
|
The
|
|
.Va 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.
|
|
.Pp
|
|
Only the
|
|
.Dv NULL
|
|
and the
|
|
.Dv SYS
|
|
style of authentication is discussed here.
|
|
.Sh Routines
|
|
.Bl -tag -width authsys_create_default()
|
|
.It 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
|
|
.Fn auth_destroy .
|
|
.It 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.
|
|
.It Fn authsys_create
|
|
Create and return an RPC authentication handle that contains
|
|
.Dv AUTH_SYS
|
|
authentication information.
|
|
The parameter
|
|
.Fa host
|
|
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.
|
|
.It Fn authsys_create_default
|
|
Call
|
|
.Fn authsys_create
|
|
with the appropriate parameters.
