-.Pp -See -.Sx DESCRIPTION -for function declarations. +.Fd #include <rpc/rpc.h> +.Fd #include <netconfig.h> .Sh DESCRIPTION -These routines allow C programs to make procedure -calls on other machines across the network. -First, the client calls a procedure to send a -data packet to the server. -Upon receipt of the packet, the server calls a dispatch routine -to perform the requested service, and then sends back a -reply. -Finally, the procedure call returns to the client. -.Pp -Routines that are used for Secure -.Tn RPC ( DES -authentication) are described in -.Xr rpc_secure 3 . -Secure -.Tn
