Question:
I have Borland C++ 4.52. If I write a program that includes
 in Win32, I dont have any problems. The project
automatically finds all the functions defined in the header file.
If I use the exact same project, but change the target to
Windows 3.x(16bit), and I try to recompile, I get undefined
function errors when linking. Additionally, there is no
bc45\libs\winsock.lib.
I finally got the program to work in 16bit mode with a 3rd party
winsock.lib.
What am I missing here? What is the difference between
the 16 and 32 bit libs that I dont understand? Why is there no
Winsock.lib and why do I have to include it in the 16 bit and
not the 32 bit?
Answer:
Winsock is provided by Microsoft as part of the WIN9x and WINNT
operating systems. As such, it is automatically linked in when
you build a WIN32 app. It is not, however, part of Windows 3.11
or WFW so you must provide the library yourself when you build a
16 bit app. You can use IMPLIB to make an import library for
winsock.dll and then include the import library in your project.
