Chapter 29 - TCP/IP Services Reference / Constants and Data Types

Internet Address Structure

You use the internet address structure when providing a TCP or UDP address to the Open Transport functions OTConnect, OTSndURequest, and OTBind. You can use the OTInitInetAddress function to fill in an internet address structure. The internet address structure is defined by the InetAddress data type.

struct InetAddress {
      OTAddressType  fAddressType;
      InetPort       fPort;      
      InetHost       fHost;      
      UInt8          fUnused[8]; 
};
typedef struct InetAddress InetAddress;

Field Description

fAddressType

The address type. The field should be AF_INET, which identifies the structure as an InetAddress.

fPort

The port number.

fHost

The 32-bit IP address of the host.
