From: ts Date: 2000-05-30T14:37:16+02:00 Subject: [ruby-talk:03035] rb_thread_wait_for / rb_thread_schedule I need, for an extension, to use rb_thread_wait_for() and rb_thread_schedule() and these functions are only in intern.h. Can I safely use it (i.e. they�ll always be available in ruby >= 1.6) ? If not, what function can I use ? Guy Decoux
