I propose to look for a particular value to do it as transaction functions do with TRANS_STATE_INTERRUPTED.Dave Reisner <d at falconindy.com> a écrit :On Aug 25, 2015 7:04 AM, "Guillaume Benoit" <guillaume at manjaro.org> wrote:

Presumably, you can't use SIGINT because you can't guarantee which
thread the signal is delivered to. You need to properly guard against
this situation by blocking SIGINT on threads which aren't the caller of
trans_commit. With only 1 thread not masking SIGINT, the linux kernel
will guarantee delivery to this thread.

Is this correct? Or is there some other reason that you can't rely on
signal delivery as an interrupt mechanism?
