cc [flags…] –I /usr/cluster/include file –L /usr/cluster/lib –l dsdev#include <rgm/libdsdev.h> scha_err_t scds_simple_probe(scds_handle_t handle, const char *hostname, int port, time_t timeout);
The scds_simple_probe() function is a wrapper function around connect(3C) and close(2) to run under a timeout.
Retrieve the hostname with either scds_get_rg_hostnames(3HA) or scds_get_rs_hostnames(3HA).
Consider using scds_simple_net_probe(3HA) instead of this function.
The following parameters are supported:
The handle returned by scds_initialize(3HA).
Internet hostname of the machine to which to connect.
Port number with which to make the connection.
Timeout value in seconds (to wait for a successful connection).
The scds_simple_probe() function returns the following:
The function succeeded.
The function failed.
Indicates that the function succeeded.
Indicates that the function timed out.
See scha_calls(3HA) for a description of other error codes.
