[LV]: Has anyone investigated making use of Critcl to create an HTML rendering widget, perhaps based on [BrowseX]?

[JCW]: Yep, Tkhtml can be built with Critcl, though it's tricky.
See [http://www.equi4.com/critlib/rhtml.README], now in critlib.

Has someone looked at http://root.cern.ch/root/Cint.html

as a possible way to integrate C with Tcl without having to compile C...

[SWT]: 
I have built a working cint shared lib for tcl.
It works great!
Now to "run" c code the cint library is only
needed for each platform that support is required for.

[Brian Theado] 17Dec2004 - Examples with Tcl_Obj* return type

The presence of Tcl_IncrRefCount is crucial here and nothing gets returned without it.  I guess Critcl automatically decrements the reference count on this return type.  Could someone provide a counter example where the automatic reference count decrement is useful?
 package require critcl
 critcl::cproc abc {} Tcl_Obj* {
    char test[4] = "abc";
    Tcl_Obj * rv = Tcl_NewStringObj ("abc", 3);
    Tcl_IncrRefCount (rv);
    return rv;
 }
 critcl::cproc 123 {} Tcl_Obj* {
    char test[3] = {1, 2, 3};
    Tcl_Obj * obj = Tcl_NewByteArrayObj (test, 3);
    Tcl_IncrRefCount (obj);
    return obj;
 }
 puts [abc]
 binary scan [123] H* result
 puts $result
Output:
 abc

''2006-11-21 [dzach]'' Could someone post a basic critcl snipet on how to access the [snack] sound library? Play a sound or record a sound, for instance?
