You could create your own epoll descriptor, register the driver fd with that, and wait on the epoll descriptor using libevent with EV_READ. Basically, the epoll descriptor would act as a proxy. Clean and simple, presuming you'd have to write some Linux specific, #ifdef'd code either way. *********************************************************************** To unsubscribe, send an e-mail to majord...@freehaven.net with unsubscribe libevent-users in the body.
