cc [flags…] –I /usr/cluster/include file –L /usr/cluster/lib –l dsdev#include <rgm/libdsdev.h> scha_err_t scds_simple_net_probe(scds_handle_t handle, scds_netaddr_t addr, time_t timeout, scds_fmsock_status_t *status, int count);
The scds_simple_net_probe() function is a wrapper function around scds_fm_net_connect(3HA) and scds_fm_net_disconnect(3HA). For hosts that have multiple mappings, scds_simple_net_probe()handles both IPv4 and IPv6 addresses for the supplied hostname.
You can retrieve a list of network addresses for the resource by using scds_get_netaddr_list(3HA).
The status for a connect to, or disconnect from, an IPv4 target is stored in the first member of the scds_fmsock_status_t array. The second member contains the status for an IPv6 target. If the hostname that is supplied to this function does not contain an IPv4 or IPv6 mapping, the corresponding status is set to SCDS_FMSOCK_NA.
The following parameters are supported:
The handle returned by scds_initialize(3HA).
The hostname, TCP port number, and protocol identifier that specify where the process is listening.
The timeout value in seconds to wait for a successful connection. Each socket (IPv4 or IPv6) gets the same timeout period, and timeouts proceed in parallel.
Array of SCDS_MAX_IPADDR_TYPES members of type scds_fmsock_status_t. Each member in the array holds a status. This parameter is an output argument that is set by this function.
The number of members in the socklist array. Set this parameter to SCDS_MAX_IPADDR_TYPES.
The scds_simple_net_probe() function returns the following values:
The function succeeded.
The function was called with invalid parameters.
At least one connect operation failed due to a timeout, a refused connection, or some other error. Inspect the err field of all members of the socklist array that are set to SCDS_FMSOCK_ERR to determine the exact error.
At least one connect or disconnect operation failed. You can inspect the scds_fmsock_status_t array to determine if the failure was in an IPv4 target, an IPv6 target, or both.
Indicates that the function succeeded.
Indicates that an internal error occurred while the function was executing.
Indicates that the connection request was refused by the server.
Indicates that the connection request timed out.
