scha_err_t scds_simple_probe(scds_handle_t handle, const char *hostname,
     int port, time_t timeout);

Description

The scds_simple_probe() function is a wrapper function around connect(3SOCKET) 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.

hostname

Internet hostname of the machine to which to connect.

0

The function succeeded.

nonzero

Errors

SCHA_ERR_NOERR

Indicates that the function succeeded.
