RFCSDK programming to check RFC destinations if working

Hi all,

I'm trying to develop a C program using RFCSDK in order to monitor whether RFC R/3 connections (as listed in SM59) are working or not. I've been reading the sample codes under .../rfcsdk/text such as sapinfo.c and srfctest.c but I've not made any good progress about it.

How can I modify the existing code in order to suit my needs?

Regards,

Chipi.
