Modules
	Port
	4-byte number used by RTI Connext to distinguish between receivers of messages on the same interface (address).
	Interface
	Abstraction of a Transport-Plugin network interface.
	Transport Priority
	A QoS set in DDS DataWriters, that is passed to the Transport Plugin when creating SendResources.

Data Structures
struct	NDDS_Transport_Buffer_t
	Generic buffer to hold data, described by a pointer to the data and length of the data. More...
struct	TransportAllocationSettings_t
	Allocation settings used by various internal buffers. More...

Macros
#define	NDDS_TRANSPORT_ALLOCATION_SETTINGS_MAX_COUNT_UNLIMITED   (-1)
	The constant used as 'unlimited' for the 'max_count' field of the structure TransportAllocationSettings_t.
#define	NDDS_TRANSPORT_ALLOCATION_SETTINGS_INCREMENTAL_COUNT_AUTOMATIC   (-1)
	The constant used as 'automatic' for the 'incremental_count' field of the structure TransportAllocationSettings_t.
#define	NDDS_TRANSPORT_ALLOCATION_SETTINGS_DEFAULT
	The constant used as default value for the struct TransportAllocationSettings_t.

Detailed Description

Basic types and macros provided by NDDS for use in the NDDS Transport-Plugin interface.

Macro Definition Documentation

#define NDDS_TRANSPORT_ALLOCATION_SETTINGS_MAX_COUNT_UNLIMITED   (-1)

The constant used as 'unlimited' for the 'max_count' field of the structure TransportAllocationSettings_t.

#define NDDS_TRANSPORT_ALLOCATION_SETTINGS_INCREMENTAL_COUNT_AUTOMATIC   (-1)

The constant used as 'automatic' for the 'incremental_count' field of the structure TransportAllocationSettings_t.

Automatic means the buffer size will double at every reallocation.

#define NDDS_TRANSPORT_ALLOCATION_SETTINGS_DEFAULT

Value:

{                                \
        2L, /* initial_count */                                                     \
        NDDS_TRANSPORT_ALLOCATION_SETTINGS_MAX_COUNT_UNLIMITED, /* max_count */     \
        NDDS_TRANSPORT_ALLOCATION_SETTINGS_INCREMENTAL_COUNT_AUTOMATIC /* incremental_count */ \
}

The constant used as default value for the struct TransportAllocationSettings_t.

The default value defined in this constant, sets the buffer to have:

• initial_count = 2 elements
• max_count = NDDS_TRANSPORT_ALLOCATION_SETTINGS_MAX_COUNT_UNLIMITED
• incremental_count = NDDS_TRANSPORT_ALLOCATION_SETTINGS_INCREMENTAL_COUNT_AUTOMATIC
