NAME    [Toc]    [Back]

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

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #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    [Toc]    [Back]

     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.

ROUTINES    [Toc]    [Back]

     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.
