Functions

  • Abort the current process.

  • dup3fd
    Duplicate a file descriptor, the caller can force the close-on-exec flag to be set for the new file descriptor by specifying O_CLOEXEC in flags.
  • epoll_create(select or epoll) and epoll
    Creates a new epoll instance.
  • epoll_ctl(select or epoll) and epoll
    Control interface for an epoll file descriptor
  • epoll_wait(select or epoll) and epoll
