Time-out Changes

After sending a request to the server, a client program waits for a default period (25 seconds) to receive a reply. You can change this timeout by using the clnt_control() routine. See Standard Interfaces for additional uses of the clnt_control() routine. See also the rpc(3NSL) man page. When considering time-out periods, be sure to allow the minimum amount of time required for “round-trip” communications over the network. The following code example illustrates the use of clnt_control().

struct timeval tv;
CLIENT *clnt;
clnt = clnt_create( "somehost", SOMEPROG, SOMEVERS, "visible" );

if (clnt == (CLIENT *)NULL)
	exit(1);
tv.tv_sec = 60;	/* change time-out to 60 seconds */
tv.tv_usec = 0;
clnt_control(clnt, CLSET_TIMEOUT, &tv);
