Man page says it specifies the length of the sockaddr structure pointed to by the address argument.
But why bind() can't figure out the length itself, since the first member (eg:AF_INET or AF_INET6...) of sockaddr structure implies the actual structure which contains it. So I think bind() can figure out the length of the sockaddr structure by inspecting address->sa_family.
You may say that, these strctures are diffrent in different OS. But the implemnetation of bind() can also be designed for diffrent OS. The length of these structures are constant in the same OS.
Who can explain it?
Thx!!!

I am attempting to set up bind on an AIX 5.3 machine. I ahve created a named.conf, db.cache (for root domain and hint file) and a db.domainname file for the host entries.

getpeername
getpeername(3XNET) X/Open Networking Services Library Functions getpeername(3XNET)NAME
getpeername - get the name of the peer socket
SYNOPSIS
cc [ flag ... ] file ... -lxnet [ library ... ]
#include <sys/socket.h>
int getpeername(int socket, struct sockaddr *restrict address, socklen_t *restrict address_len);
DESCRIPTION
The getpeername() function retrieves the peer address of the specified socket, stores this address in the sockaddr structure pointed to by
the address argument, and stores the length of this address in the object pointed to by the address_len argument.
If the actual length of the address is greater than the length of the supplied sockaddr structure, the stored address will be truncated.
If the protocol permits connections by unbound clients, and the peer is not bound, then the value stored in the object pointed to by
address is unspecified.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The getpeername() function will fail if:
EBADF The socket argument is not a valid file descriptor.
EFAULT The address or address_len parameter can not be accessed or written.
EINVAL The socket has been shut down.
ENOTCONN The socket is not connected or otherwise has not had the peer prespecified.
ENOTSOCK The socket argument does not refer to a socket.
EOPNOTSUPP The operation is not supported for the socket protocol.
The getpeername() function may fail if:
ENOBUFS Insufficient resources were available in the system to complete the call.
ENOSR There were insufficient STREAMS resources available for the operation to complete.
