rpc_clnt_auth: auth_destroy, authnone_create, authsys_create,
authsys_create_default - library routines for client side remote
procedure call authentication
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 [Toc] [Back]
The following routines require that the header rpc.h be included [see
rpc(3N) for the definition of the AUTH data structure].
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
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(const char *host, const uid_t uid, const gid_t gid,
const int len, const gid_t *aup_gids);
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.
Call authsys_create with the appropriate parameters.
