Re: unload state

* how can I detemine when the library is really detached and I can

I only found " When both reference counts have reached 0, the
library will be detached from the process.".
But how can I find this either on C or Tcl level.

I don't about Windows or Mac, but for POSIX conforming systems have a
look at the dlopen()/dlclose() interfaces - and read very carefully.

You can't unload a C extension from Tcl up to and including 8.4. For
a possibility with 8.5 have a look here: http://wiki.tcl.tk/10852

* what is the preferred way to do a unload? Currently there is no API
in the "package" command.
May be something new like "package unload..."

[package] is for Tcl packages. Plain Tcl packages can be forgotten:
package forget foo
