Establishing a connection

To establish a connection with an REXEC server, use the rexecve call:

#include <rx.h>

int	cnum;			/* rexec connection number */

main()
{
	char	host[20],		/* host name */
		service[20],	/* service name */
		*rxargv[10],	/* service argument vector */
		*rxenvp[10];	/* service environment vector */
	int	flags = 0;	/* service flags */
	extern long	Rx_errno;	/* rexec error */

	(void) strcpy(host, "tahoe");
	(void) strcpy(service, "rx");
	rxargv[0] = "ls";
	rxargv[1] = "-l";
	rxargv[2] = NULL;
	rxenvp[0] = NULL;

	cnum = rexecve(host, service, rxargv, rxenvp, flags);
	if (cnum < 0) {
		rxperror(Rx_errno);
		exit(1);
	}
.
.
.
}

Upon successful completion, rexecve will allocate and return a connection number, which should be used for all subsequent calls to REXEC client routines for this connection.
