RPC_CLNT_AUTH(3NSL) Networking Services Library Functions RPC_CLNT_AUTH(3NSL)


NAME


rpc_clnt_auth, auth_destroy, authnone_create, authsys_create,
authsys_create_default - library routines for client side remote
procedure call authentication

SYNOPSIS


#include <rpc/rpc.h>


void auth_destroy(AUTH *auth);


AUTH *authnone_create(void);


AUTH *authsys_create(const char *host, const uid_t uid, const gid_t gid,
const int len, const gid_t *aup_gids);


AUTH *authsys_create_default(void);


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. For
the DES style authentication, please refer to secure_rpc(3NSL).


The NULL and SYS style of authentication are safe in multithreaded
applications. For the MT-level of the DES style, see its pages.

Routines


Note: See rpc(3NSL) for the definition of the AUTH data structure.


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.
