This structure varies depending on the protocol selected. Except for the sa_familymember, sockaddrcontents are expressed in network byte order.
Syntax
struct sockaddr {
u_short
sa_family;
char
sa_data[14];
};
|
Members
- sa_family
-
Address family.
- sa_data[14]
-
Contains the address in a protocol-dependent format.
Remarks
For Winsock functions that use
sockaddr, the
nameparameter is not strictly interpreted as a pointer to a
sockaddrstructure. It is presented in this manner for
Windows Sockets compatibility. The actual structure is interpreted
differently in the context of different address families. The only
requirements are that the first
u_shortis the address family and the total size of the
memory buffer in bytes is
namelen.
The following structure declaration is used with TCP/IP. Other protocols use similar structures.
