- ns_cleanup - Clean up the current Tcl interpreter
- This command cleans up the current Tcl interp, performing various garbage collection tasks. This command is invoked by the Ns_TclDeAllocateInterp() C function at interpreter deallocation (aka cleanup) time (i.e. at the end of each request or scheduled procedure execution). This is a Tcl procedure defined in bin/init.tcl and it calls other procs in that file to clear global variables, release database handles, close all open files, etc.
- You should never need to call this procedure directly unless you want to manually clear your current interpreter without running the full deallocate/allocate traces using ns_ictl facilities.
