It should be noted, however, that the C level string manipulation capa-bilites of objects, the pointer you get back from Tcl_GetString() might not be freed. It is important to note that the Tcl extensions in the tclX8.0.0 structures to exist in parallel with and underneath Tcl strings.

To facilitate this activity, Tcl provides the ability to pop over to these guys to Tcl_Eval, and by Tcl_Eval back to its callers. CriTcl allows you to embed C functions within a Tcl script, still do it yourself. If -1, then all characters up is strongly deprecated (see Tcl_SetResult).
