SOCKADDR Structure

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at SOCKADDR Structure.

The SOCKADDR structure is used to store an Internet Protocol (IP) address for a machine participating in a Windows Sockets communication.

struct sockaddr {  
    unsigned short sa_family;  
    char sa_data[14];  
};  

Parameters

sa_family
Socket address family.

sa_data
Maximum size of all the different socket address structures.

The Microsoft TCP/IP Sockets Developer's Kit only supports the Internet address domains. To actually fill in values for each part of an address, you use the SOCKADDR_IN data structure, which is specifically for this address format. The SOCKADDR and the SOCKADDR_IN data structures are the same size. You simply cast to switch between the two structure types.
