The epoll API was introduced in Linux kernel 2.5.44. Support was added to glibc in version 2.3.2. CONFORMING TO top The epoll API is Linux-specific. Some other systems provide similar mechanisms, for example, FreeBSD has kqueue, and Solaris has /dev/poll. NOTES top

I'm reading Linux Device Driver 3rd. In chapter 6: poll and select, the author says: "*unsigned int (*poll) (struct file *filp, poll_table wait); The driver method is called whenever the user-space program performs a poll, select, or epoll system call involving a file descriptor associated with the driver."

In this repo it is said that "Linux has limited support for using epoll as a mechanism for asynchronous I/O [...] if the file is opened as O_NONBLOCK, then a read will return EAGAIN until the relevant part is in memory", which contradicts this answer. But in a simple test I couldn't confirm that.

Epoll vs Select/Poll. We can add and remove file descriptor while waiting; epoll_wait returns only the objects with ready file descriptors; epoll has better performance – O(1) instead of O(n) epoll can behave as level triggered or edge triggered (see man page) epoll is Linux specific so non portable .

epoll is a Linux kernel system call for a scalable I/O event notification mechanism, first introduced in version 2.5.44 of the Linux kernel mainline. Its function is to monitor multiple file descriptors to see whether I/O is possible on any of them.
