 RPC_CLNT_AUTH 3NSL "Feb 18, 2015"
 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.
