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 host argument 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 arguments.
AVAILABILITY¶
These functions are part of libtirpc.
