RPC_CLNT_AUTH(3) BSD Library Functions Manual RPC_CLNT_AUTH(3)
NAME
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 pro-
grams 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 au-
thentication 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 authentica-
tion information associated with auth. De-
struction usually involves deallocation of pri-
vate data structures. The use of auth is unde-
fined after calling auth_destroy().
authnone_create() Create and return an RPC authentication handle
that passes nonusable authentication informa-
tion 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 informa-
tion. The host argument is the name of the ma-
chine on which the information was created; uid
is the user's user ID; gid is the user's cur-
rent group ID; len and aup_gids refer to a
counted array of groups to which the user be-
longs.
authsys_create_default() Call authsys_create() with the appropriate ar-
guments.
AVAILABILITY
These functions are part of libtirpc.
