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

       SYNOPSIS
             cc [options] file -lnsl
             #include <rpc/rcp.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_creat_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.  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].

             void
             auth_destroy(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 auth_destroy.

             AUTH *
             authnone_create(void);

                   Create and return an RPC authentication handle that
                   passes nonusable authentication information with each
                   remote procedure call.  This is the default

      rpc_clnt_auth(3N)                                  rpc_clnt_auth(3N)


                  authentication used by RPC.

            AUTH *
            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.

            AUTH *
            authsys_create_default(void);

                  Call authsys_create with the appropriate parameters.
