I would see it as an "open issue" (or more a bug) for a specific implementation detail where I would like to recommend a few corrections. The expectations from an information in the documentation like the following can not be completely satisfied at the moment. 'ev_feed_signal (int signum) This function can be used to "simulate" a signal receive. It is completely safe to call this function at any time, from any context, including signal handlers or random threads.' http://linux.die.net/man/3/ev > As far as we know, the current method is already safe and robust, and > evidence to the contrary would be appreciated, but so far, none is known. I imagine that the affected function could be made async-signal-safe if all received signal numbers will be written to a dedicated pipe. http://cr.yp.to/docs/selfpipe.html > If you know of a method that allows us to do this in a practical but still > strictly c99 conforming way that would be cool, but I will not hold my breath > :) Would the pipe approach be acceptable for you? Does it make sense to choose such implementation details also by a build configuration? http://cvs.schmorp.de/libev/configure.ac?revision=1.34&view=markup Regards, Markus _______________________________________________ libev mailing list libev@lists.schmorp.de http://lists.schmorp.de/cgi-bin/mailman/listinfo/libev
