FreeTDS 0.91.96 - tdssrv/tdspool apps

Thanks Frediano for your pronto answers.

I'm in the process of testing as much as I can now (as you can see!) and I have a few extra questions:

a) What's the purpose/use of 'tdssrv'? Is it supposed to be used in conjunction with 'freeclose' test or tdspool app?
b) tdspool app doesn't seem to work at all, I'm afraid. I get this error message:

                       'Could not open initial connection 0'

plus a lovely runtime exception! Grrr!

Program received signal SIGSEGV, Segmentation fault.

By looking at some source code inside src/pool folder, I can see an issue in member.c, where it reads:

...
#if HAVE_GETHOSTNAME
...
...
#endif

However, winsockets were/are never initialised. (Note: this doesn't fix the runtime exception)

I need some help with the runtime exception. My C language knowledge is less than basic!

Thanks again.

Sergio.
