Constants and Data Types

Endpoint Service Types

Open Transport uses the servtype field of the TEndpointInfo structure (page 3-48) to indicate the kind of service the endpoint provides. The constant names that Open Transport can return for this field are given by the endpoint service enumeration:

enum {
      T_COTS         = 1,
      T_COTS_ORD     = 2,
      T_CLTS         = 3,
      T_TRANS        = 5,
      T_TRANS_ORD    = 6,
      T_TRANS_CLTS   = 7   
};
