RPC_CLNT_AUTH(3)         BSD 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

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 associ‐
                               ated 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 ma‐
                               chine 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.

AVAILABILITY
     These functions are part of libtirpc.
