I'm not a C programmer but I spent some time analysing major parts of C code for a SAP integration library that I maintained to get a better understanding of the SAP RFC interfaces. Never had an issue with the C code and TCL side of the integrations very easy to reason and maintain whilst covering massive amounts of integrations to SAP. More often then not, the problems I was involved with resolving on emergency escalation (line down) calls was on the SAP side of the world and never in the integration code in TCL and C. The biggest drawback with the TCL implementation from our application vendor was that they did not implement multi threading for TCL and instead implemented a node.js like event loop. As SAP calls were locking, this did cause locks for all other TCL calls.
