Wiki pages with Critcl examples (incomplete list):
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 [L1 ], 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 010203
