''unload ?switches? fileName ?packageName? ?interp?'' Eventually, the doc should appear here: http://www.purl.org/tcl/home/man/tcl8.5/TclCmd/unload.htm New command in Tcl 8.5. See TIP 100 [http://tip.tcl.tk/100] from [George Petasis] for where it came from. ---- Hints for extension authors who want to have an unloadable extension: * Be prepared for extra work when using a custom Tcl_Object type with non-NULL freeProc * Be extremly careful in your use of TSD ([Thread] Specific Data) * Be prepared for trouble if your extension involves the [VFS] layer * ... ---- [JH]: Note that TIP 239 [http://tip.tcl.tk/239] will likely change the '''unload''' command before 8.5 is final. ---- [Category Command]
