AIX Version 4.3 Differences Guide

The send_file call only supports the TCP/IP protocol. In other words, the sockets
of type SOCK_STREAM in address family AF_INET. Both blocking and
non-blocking connections are supported. In blocking mode, send_file blocks until
all of the file data has been transmitted. In non-blocking mode, or in the event
send_file is interrupted, the system call updates parameters in the sf_parms
structure to indicate the amount of data that has actually been transmitted.
4.11 Binder Library Enhancements (4.3.2)
The binder library, libld.a, that provides functions to allow an application to create
and manipulate XCOFF object files, has been enhanced in AIX Version 4.3.2 to
support a cross mode environment.
This allows 32-bit applications to create and manipulate both 32-bit and 64-bit
objects using a consistent interface. The changes also allow 64-bit objects to
create and manipulate both 32-bit and 64-bit objects. The functions in the library
transparently open both 32-bit and 64-bit object files, as well as both small format
and large format archive files.
An application need not know the format of an object file before opening it. It can
call the ldopen function and then check the magic number of the file or archive
member.
