calling Winsock??

[George R. Gonzalez]

Hi, I have an old DOS 16-bit borland C program that would REALLY benefit
from being able to make some WINSOCK calls.

I have PowerPak for DOS, so if I read the manual correctly, I can make calls
to 16-bit DLL's, which WINSOCK is one of.

problem is, I always get "invalid entrypoint called" as soon as I hit the
first call to "socket".

The linker didnt complain, and there's clearly a "SOCKET" listed on the link
map.

So what's wrong? Any ideas, examples?

environment: Windows/XP, WOW, BCC 4.5, PowerPak.

Thanks,

George

I believe the technique used only works on Windows 3.1, 9x, and ME. Windows XP
is really NT 6 which does not work the same. I had the same problem with a DJGPP
library that used Winsock, but would not work under NT.
