Changes or retrieves various information about a client object.
#include <rpc/rpc.h>
bool_t clnt_control (cI, req, info) CLIENT *cl; int req; char *info;
The clnt_control macro is used to change or retrieve various information about a client object.
User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) have the following supported values for the req parameter's argument types and functions:
| Values for the req Parameter | Argument Type | Function | |
| CLSET_TIMEOUT | struct timeval | Sets total time out. | |
| CLGET_TIMEOUT | struct timeval | Gets total time out. | |
| CLGET_SERVER_ADDR | struct sockaddr | Gets server's address. |
The following operations are valid for UDP only:
| Values for the req Parameter | Argument Type | Function | |
| CLSET_RETRY_TIMEOUT | struct timeval | Sets the retry time out. | |
| CLGET_RETRY_TIMEOUT | struct timeval | Gets the retry time out. |
Notes:
- If the time out is set using the clnt_control subroutine, the time-out parameter passed to the clnt_call subroutine will be ignored in all future calls.
- The retry time out is the time that User Datagram Protocol/Remote Procedure Call (UDP/RPC) waits for the server to reply before retransmitting the request.
| cl | Points to the structure of the client handle. |
| req | Indicates the type of operation. |
| info | Points to the information for request type. |
Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
