[Libevent-users] Signals question regarding libevent

[Subbu Subramaniam]

A follow-up question.

Can the same signal be registered multiple times, each with a different void *
context? Is the expectation that the callback will be called multiple times
correct?

In the attached program, the callback function seems to be called only once,
even though it is registered two times.

I tried it in FreeBSD-4.11/libevent-1.1b, and RHEL-2.6.9/libevent-1.3e. In
Freebsd, the last registered void * is given in the callback whereas in linux,
it is the first one. But the callback happens only once.

Is this a bug?
