Purpose
Indicates that the service dispatch routine cannot complete the remote procedure call due to an error that is not covered by a protocol.
Library
C Library (libc.a)
Syntax
#include <rpc/rpc.h>
void svcerr_systemerr ( xprt)
SVCXPRT *xprt;
Description
The svcerr_systemerr subroutine is called by a service dispatch subroutine that detects a system error not covered by a protocol. For example, a service dispatch subroutine calls the svcerr_systemerr subroutine if the first subroutine can no longer allocate storage. The routine sets the status of the Remote Procedure Call (RPC) reply message to the SYSTEM_ERR condition.
Parameters
Item | Description |
---|---|
xprt | Points to the RPC service transport handle. |
Purpose
Indicates that the service dispatch routine cannot complete the remote procedure call due to an error that is not covered by a protocol.
Library
Network Services Library (libnsl.a)
Syntax
#include <rpc/rpc.h>
void svcerr_systemerr ( xprt)
const SVCXPRT *xprt;
Description
The svcerr_systemerr subroutine is called by a service dispatch subroutine when a system error occurs that can not be covered by any particular protocol. The subroutine sets the status of the remote procedure call (RPC) reply message to the RPC_SYSTEMERROR condition.
Parameters
Item | Description |
---|---|
xprt | Points to the RPC service transport handle. |

#include <rpc/rpc.h>
#include <stdlib.h>
#define PROG 0x3fffffffL
#define VERS 0x1L
