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.
