Hi, I have been reading through archives, read Mueller's recent threads article, and crawled around freebsd.org documentation but could not find an answer to this question. I am trying to port a multithreaded application from Linux to FreeBSD; the application uses SIGUNUSED signal (because Linux threads utilize SIGUSR1 and 2 for themselves). I am considering replacing SIGUNUSED with SIGUSR1 but am concerned if FreeBSD threads aren't using them also. Does anyone know if either user-level threads ( gcc -Pthread) or kernel threads (gcc -kthread) use SIGUSR1 in a way that would preclude using it in the application? Thanks a lot for any info or pointers, Michael Rabinovich
