# 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 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.
