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.
