Hi,guys I'm learning libev. But i don't understand about the ev_default_fork flag of ev_loop. Is this a question of close-on-exec?Like the FD_CLOEXEC fcntl() flag do? when i need to set the flag?which case this flag is necessary? This a description of doc:
> This function sets a flag that causes subsequent ev_loop iterationsto > reinitialise the kernel state for backends that have one. Despite thename, > you can call it anytime, but it makes most sense after forking, inthe child > process (or both child and parent, but that again makes littlesense). You > must call it in the child before using any of the libevfunctions, and it > will only take effect at the next ev_loop iteration. > On the other hand, you only need to call this function in the childprocess > if and only if you want to use the event library in the child. Ifyou just > fork+exec, you don't have to call it at all. > The function itself is quite fast and it's usually not a problem to callit > just in case after a fork. To make this easy, the function will fit inquite > nicely into a call to pthread_atfork: pthread_atfork (0, 0, > ev_default_fork);
