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_SYSauthentication 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.
