Yup! This is right. Eventually, all (ok, most) of the useful things there in C-API should be sooner or later exposed over the Tcl API. If they aren't now, means that nobody needed or asked for them. You are free to contribute Tcl wrappers to not-exposed C-API things anytime. This is how things happen, right? ;) Zoran > Rob Seeger > > Zoran Vasiljevic wrote on 8/17/2004, 10:09 AM: > > > On Tuesday 17 August 2004 16:01, Nathan Folkman wrote: > > > Off topic, but somewhat related... ;-) I know Tcl can't be used in all > > > cases, and that sometimes you have to write C code to accomplish what's > > > needed, but hopefully everyone can see the advantages of keeping as > > much > > > code as possible up at the Tcl level. > > > > > > I think we should continue to really look at the situations where folks > > > are writing C code, and try to identify the reasons: > > > > > > 1.
