NAME

       rpc_clnt_auth: auth_destroy(), authnone_create(), authsys_create(), authsys_create_default() - library routines for client side remote pro-
       cedure call authentication

SYNOPSIS


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 handle.	The field of the structure should be initialized by the 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 and the style of authentication is discussed here.  For the style authentication, please refer to secure_rpc(3N).

       The and style of authentication are safe in multithreaded applications.

       The HP-UX implementation of RPC only supports the X/Open Transport Interface (XTI).  Applications that  are  written  using  the  Transport
       Layer Interface (TLI) and wish to use RPC, must convert their application to XTI.

   Routines
       The following routines require that the header be included (see rpc(3N) for the definition of the 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 unde-
	      fined after calling

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

       Create and return an RPC authentication handle that contains
	      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   with the appropriate parameters.

MULTITHREAD USAGE

       Thread Safe:	     Yes
       Cancel Safe:	     Yes
       Fork Safe:	     No
       Async-cancel Safe:    No
       Async-signal Safe:    No

       These functions can be called safely in a multithreaded environment.  They may be cancellation points in that they call functions that  are
       cancel points.

       In a multithreaded environment, these functions are not safe to be called by a child process after and before These functions should not be
       called by a multithreaded application that supports asynchronous cancellation or asynchronous signals.

NAME

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

SYNOPSIS

       void auth_destroy(AUTH *auth);

       AUTH *authnone_create	(void)

       AUTH *authsys_create(const cha r*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. For the DES style authentication, please refer to secure_rpc(3NSL).

       The NULL and SYS style of authentication are safe in multithreaded applications. For the MT-level of the DES style, see its pages.

   Routines
       The following routines require that the header <rpc/rpc.h> be included (see rpc(3NSL) for the definition of the AUTH data structure).

	 #include <rpc/rpc.h>

       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.
