This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig4E7D4E2C509ACF61C53D1B22 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hi, How do threads interact with signals? In particular, if I have a "main" process thread (the one started by main()) which generates items for a mutex-protected queue which are consumed by a worker thread, and I need to insert an item in the queue from the signal handler, am I correct that doing pthread_mutex_lock() from the signal handler could deadlock if the signal handler is executed by any of the threads (and the mutex is non-recursive)? How is this solved in general? By recursive mutexes? --------------enig4E7D4E2C509ACF61C53D1B22 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHfU4nldnAQVacBcgRAmYaAJ9otYyttlpdgswiBBpjPaLCgxJgEQCdFUpF tDXHVbYxeYKDtFMn5YZ8kNA= =ttN4 -----END PGP SIGNATURE----- --------------enig4E7D4E2C509ACF61C53D1B22--
