[PD-dev] inverse of myclass_setup()? myclass_unsetup()?

Hi,

Say I have the following:

hsext_setup() { /* start Haskell run time system */ }

hsext_unsetup() { /* stop Haskell run time system cannot be restarted hereafter */ }

Am I correct in assuming hsext_setup() will be called at most once?

How can I ensure hsext_unsetup() is called when Pd exits?

Is atexit() the right way? Seems dirty:

---- $ man atexit

Since glibc 2.2.3, atexit() can be used within a shared library to establish functions that are called when the shared library is unloaded.

Functions registered using atexit() are not called if a process terminates abnormally because of the delivery of a signal. ----

Thanks for any ideas,

Claude
