RPC_CLNT_AUTH(3)       FreeBSD 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

LIBRARY
     Standard C Library (libc, -lc)

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
     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
     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 host argument 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
                               arguments.
