.\"O .SH SYNOPSIS AND DESCRIPTION
.SH ½ñ¼°¤ÈÀâÌÀ
.\"O These routines allow C programs to make procedure
.\"O calls on other machines across the network.
.\"O First, the client calls a procedure to send a data packet to the server.
.\"O Upon receipt of the packet, the server calls a dispatch routine
.\"O to perform the requested service, and then sends back a reply.
.\"O Finally, the procedure call returns to the client.
