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(NS) 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 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.
