RPC_CLNT_AUTH(3) Library Functions Manual RPC_CLNT_AUTH(3)
auth_destroy, authnone_create, authsys_create, authsys_create_default --
library routines for client side remote procedure call authentication
Standard C Library (libc, -lc)
authsys_create(const char *host, const uid_t uid, const gid_t gid, const
int len, const gid_t *aup_gids);
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
Only the NULL and the SYS style of authentication is discussed here.
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
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
authsys_create_default() Call authsys_create() with the appropriate
