typedef void (*CassHostListenerCallback)(CassHostListenerEvent event, const CassInet address, void *data)¶

A callback used to indicate the host state for a node in the cluster.

cass_cluster_set_host_listener_callback()

Param event:

[in]

Param address:

[in]

Param data:

[in]

cass_uint32_t cass_date_from_epoch(cass_int64_t epoch_secs)¶

Converts a unix timestamp (in seconds) to the Cassandra “date” type. The “date” type represents the number of days since the Epoch (1970-01-01) with the Epoch centered at the value 2^31.

Parameters:

epoch_secs – [in]

Returns:

the number of days since the date -5877641-06-23

cass_int64_t cass_time_from_epoch(cass_int64_t epoch_secs)¶

Converts a unix timestamp (in seconds) to the Cassandra “time” type. The “time” type represents the number of nanoseconds since midnight (range 0 to 86399999999999).

Parameters:

epoch_secs – [in]

Returns:

nanoseconds since midnight

cass_int64_t cass_date_time_to_epoch(cass_uint32_t date, cass_int64_t time)¶

Combines the Cassandra “date” and “time” types to Epoch time in seconds.

Parameters:

• date – [in]

• time – [in]

Returns:

Epoch time in seconds. Negative times are possible if the date occurs before the Epoch (1970-1-1).
