Here are the data structures with brief descriptions:

Cet_attach	Structure containing attachment info
Cet_bridge_config_t	Structure to define configuration parameters used to bridge ET systems (transfer events between 2 systems)
Cet_event_t	This structure defines an Event which exists in shared memory, holds data, and gets passed from station to station
Cet_fifo_context_t	Structure to hold the context of a fifo connection to ET
Cet_fifo_entry_t	Structure to hold the a fifo entry obtained from ET
Cet_fix	Struct to fix station's input and output linked lists after crash
Cet_fixin	Structure for fixing station input list
Cet_fixout	Structure for fixing station output list
Cet_id_t	Structure defining an ET system user id (one needed for each system in use) which contains pointers to key mem locations, config info, status info, node locality and remote node info
Cet_list_t	Structure defining a station's input or output list of events
Cet_mem_t	Structure containing info stored at front of shared or mapped memory
Cet_netthread_t	Struct for passing data from system to network threads
Cet_open_config_t	Structure holding all configuration parameters used to open an ET system
Cet_proc	Structure containing local process info
Cet_response_t	Structure for holding an ET system's single response to ET client's broad/multicast
Cet_stat_config_t	Structure to hold parameters used to configure a station
Cet_stat_data_t	Structure to hold the current state of a station
Cet_station_t	Structure defining a station
Cet_sys_config_t	Structure containing all info necessary to configure an ET system
Cet_system_t	Structure containing all ET system information
