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.
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.
