Programming Examples
LAN Programming Interface Examples
* - Windows 95, using Microsoft Visual C++ 4.0 Standard Edition
* - Windows NT 3.51, using Microsoft Visual C++ 4.0
* + Be sure to add WSOCK32.LIB to your list of libraries!
* + Compile both lanio.c and getopt.c
* + Consider re-naming the files to lanio.cpp and getopt.cpp
*
* Considerations:
* - On UNIX systems, file I/O can be used on network sockets.
* This makes programming very convenient, since routines like
* getc(), fgets(), fscanf() and fprintf() can be used. These
* routines typically use the lower level read() and write() calls.
*
* - In the Windows environment, file operations such as read(), write(),
* and close() cannot be assumed to work correctly when applied to
* sockets. Instead, the functions send() and recv() MUST be used.
