Have the functions suspend/resume a sens for a thread?

I don't think so. This is far more dangerous than interruption, since a suspended thread may still hold locks. If you want to suspend a thread, have it check a shared data structure periodically and block with a condition variable if a "suspend" flag is set until that flag becomes clear again.
