int Ns_TclFreeSet( Tcl_Interp *interp, char *setId );
Ns_TclFreeSet frees the set specified by the set ID for the interpreter. If the set was initially entered with the NS_TCL_SET_DYNAMIC flag with Ns_TclEnterSet, the actual Ns_Set is also freed. Otherwise, the actual Ns_Set is not freed and the programmer is responsible for eventually freeing it.
The ns_set free Tcl function calls this function.
