#include <rpc\rpc.h>

bool_t
svc_sendreply(xprt, outproc, out)
SVCXPRT *xprt;
xdrproc_t outproc;
char *out;

Parameters

xprt

Pointer to the caller's transport handle.

XDR procedure that encodes the results.

Pointer to the results.

Description

The service dispatch routine calls the svc_sendreply() call to send the results of the call to the caller.

Return Values

The value 1 indicates success; the value 0 indicates an error.
