fnvoid addFd(int fd, FdEvent events, FdHandler handler) nothrow @nogc

`fd`	File descriptor to monitor
`events`	Events to monitor (FdEvent flags)
`handler`	Callback delegate Example: `import core.sys.posix.unistd : pipe; int[2] fds; pipe(fds); addFd(fds[0], FdEvent.read, (fd) nothrow @nogc { // Data available to read });`

fnvoid addFd(int fd, FdHandler handler) nothrow @nogc

Convenience function equivalent to addFd(fd, FdEvent.read, handler).

`fd`	File descriptor to monitor
