Inside Macintosh: Networking With Open Transport / Part 2 - Open Transport Reference

Chapter 22 - Endpoints Reference / Constants and Data Types

Endpoint Flags

Open Transport uses the flags field of the TEndpointInfo structure to specify additional information about the endpoint. The constant names that Open Transport can return for this field are given by the endpoint flags enumeration:

enum {
      T_SENDZERO          = 0x001,
      T_XPG4_1            = 0x002,
      T_CAN_SUPPORT_MDATA = 0x10000000,
      T_CAN_RESOLVE_ADDR  = 0x40000000,
      T_CAN_SUPPLY_MIB    = 0x20000000
};

Constant descriptions

T_SENDZERO

This endpoint lets you send and receive zero-length TSDUs.

T_XPG4_1

This endpoint supports the OTGetProtAddress function ( conforms to XTI in XPG4).

T_CAN_SUPPORT_MDATA

This endpoint supports M_DATA, that is, it permits receiving and returning raw packets. For additional information, see "Advanced Topics".
