NAME
rpc_clnt_auth: auth_destroy, authnone_create,
authsys_create, authsys_create_default - library rou-
tines for client side remote procedure call authentica-
tion
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. First, the
client calls a procedure to send a data packet to the
server. Upon receipt of the packet, the server calls a
dispatch routine to perform the requested service, and then
sends back a reply.
These routines are normally called after creating the CLIENT
handle. The client's authentication information is passed
to the server when the RPC call is made.
Routines
The following routines require that the header rpc.h be
included [see rpc(3N) for the definition of the AUTH data
structure].
#include <rpc/rpc.h>
void
authdestroy(AUTH *auth);
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 authdestroy.
AUTH *
authnonecreate(void);
Create and return an RPC authentication handle that
passes nonusable authentication information with each
remote procedure call. This is the default authentica-
tion used by RPC.
AUTH *
authsyscreate(const char *host, const uidt uid, const gidt gid,
const int len, const gidt *aupgids);
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.
